Is Globalization the Main Culprit for the 2008 Global Financial Crisis

The global financial crisis that began in late 2007 but erupted in 2008 was considered one of the worst threats to the global economy. The global financial crisis was characterized by credit crunch and the collapse of stock markets.Advertising We will write a custom research paper sample on Is Globalization the Main Culprit for the 2008 Global Financial Crisis? specifically for you for only $16.05 $11/page Learn More The results of the crisis were massive since it led to the evaporation of investment decisions by firms, loss of jobs and loss of income. There was generally an economic recession in majority of the developed world and hence it slowed economy in the developing world. It is true that globalization is linked to the global financial crises. I agree that globalization is the main culprit of the financial crises; this is largely because the agents of globalization are largely associated with the emergence of global financial crises as will be exp lained below: Main Analysis Globalization can be defined as the intensification of trade and other economic activities between countries of the globe in terms goods, services and also investment. After the cold war, majority of the countries embraced the basic principles of globalization like free trade. The plain understanding of globalization is in the perspective of free trade, the function of foreign company and trade. Globalization as a phenomenon is often linked with financial de regulation and the neo liberal economic revolution; but the Asian financial crisis, the Enron scandal and the growing inequalities together with the financial crisis have lead to more concerns on the neo-liberal strategy. The negative effects of globalization on a national economy can be so disastrous according to the works of Joseph Stiglitz. There has been a lot of opposition to globalization since it is associated with the volatility of commodity prices and its impact on the distant economies. The ever spiraling increase in the global prices of food and fuel is considered a result of globalization. In the 2008, for example, the surge in the prices of fuel and food commodities which are the fundamental commodities in the global market negatively impacted on the world economy. The main reason why there was an increased volatility in the global market during the 2008 financial crisis as opposed to other crisis is due to the globalized economy (Turner and Khondkar 42).Advertising Looking for research paper on business economics?

Financial liberalization involves the elimination of tari ffs, and duties have resulted in an unrestricted cross border transaction. The 2008 economic crisis was largely associated to the collapse of the Lehman bothers, which was the largest American investment bank; this brought to fore the function and the capacity of state institutions and revived the debate that despite the growth of globalization forces, there should always an efficient state structure (Turner and Khondkar 58). The trend of globalization had been increasing after the end of the cold war when America was declared the world superpower following the collapse of the USSR. This trend of globalization had been characterized by the increasing levels of trade, intensified movement of people and the advancement of technology that has brought the people and the entire world into a closer economic, political and cultural unit. It is this increasing independence that led to the 2008 global financial crises due to the fact that the monumental accumulation of global debt in the Ame rican financial institutions was unsound. The 2008 economic crisis had roots in the 1997 financial crisis in the Asian region; after the collapse of the Asian markets, people opted for the USA as a favorite investment destination. This led to the increase in the value of stock market and the rise in the price of housing. This movement of capital from one location to another like for example the Asian Region to the US was made possible by globalization and hence globalization is directly linked to the global financial crisis of 2008 (Bulliet et al 824). The institutionalization of global phenomenon like the financial globalization has contributed to the increase in the inequality gap between the developed and the developing countries; this is largely associated with international capital flows. Financial globalization was touted as the best mode of enhancing savings, relax the credit stress, and improve the income of the developing countries and to stimulate economic growth.Advertisi ng We will write a custom research paper sample on Is Globalization the Main Culprit for the 2008 Global Financial Crisis? specifically for you for only $16.05 $11/page Learn More This was never to be the case as financial globalization could not meet these expectations but instead it helped intensify economic instability. Trade liberalization together with its expected impact like prospect of economic growth, employment and income inequality came under close scrutiny. The emergence of financial globalization and wealth inequality has resulted in the unequal flows of capital and also uneven progress in the opening of capital accounts; unlike in Asia and Western countries, those of Africa and the Latin America have lagged behind in opening their capital accounts. The world has witnessed uneven financial globalization which is linked to the global financial crises (ILO report 39). Emmerich and the group in their book titled Globalization 2.0: roadmap to t he future from leading minds have identified seven virtues of globalization and in these virtues, one has been linked to the global financial crisis, and this is the thrift; Emmerich, Ijioui and Ceyp related this virtue with 2008 global financial crisis and the increasing opulence in some parts of the world. They argued that in the western world, people had socialized themselves with the period of cheap money and hence they considered it primitive to save money leading to the decline in savings in Anglo-Saxon countries like the Britain, Canada and the US. These countries were paragon of economic and financial culture and hence they adopted the culture of non-saving. When the global recession hit, commercial banks had run out of savings, the population had little to spend and hence generally low liquidity level which resulted in the collapse of commercial banks (Emmerich, Ijioui and Ceyp 80). When the global financial crisis is analyzed in the context of globalization, then the insta bility that is created by the speculation about trade is worth mentioning.Advertising Looking for research paper on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More The global financial crises did not only concern the financial markets but also the international institutions and its productive structure since globalization is controlled at the core and its effects will only be triggered at the center and will be felt across the globe as exemplified by the 2008 crisis that was triggered by the financial markets in the USA and was felt all over the globe. Due to the forces of globalization, financial crisis can be mad-made; the realization that the global world desperately needs oil and the fact the Washington consensus legalized trade liberalization makes the world vulnerable to the whims of cartels, especially if they have the knowledge and the ability to determine the timelines of the speculative course and the subsequent collapse of the speculation who can take advantage of speculative trade to push the prices of crude oil upwards (Chodussudovsky 1). Conclusion The occurrence of the global financial crisis in the year 2008 was considered glob alization at its death-bed; there was an imminent dissolution of the globalized world. This was further exacerbated by the fact that the global financial crisis was followed by the world economic crisis, which was a reflection of how the global chain reaction can be triggered and can interact to pull a destructive fashion. There have been some demands that the goals of globalization should be redefined that is; world leaders should consider other ways of cooperation and also they should create institutions that should be used in solving international disputes. With the current developments with regard to the three forms of globalization; global markets, infrastructural development and global corporations, then the future appear bleak since these forms of globalization are man-made and hence volatile and prone to suffering from the vagaries of nature. Globalization has led to simultaneous impoverishment of individuals from different nations largely due to the global market mechanism factor. The several global financial crises are not only due to the volatility of the financial markets but also due to the collapse of state institutions and the development of rapid profit ventures.

Application of 2-D gas chromatography for environmental analysis Abstract Application of 2-D gas chromatography for environmental analysis Abstract IntroductionPrinciple for Two-Dimensional Gas Chromatography (GCÃâ€"GC)Application of GCÃâ€"GC in Environmental AnalysisAnalysis of PCBs, PCDDs and PCDFsPesticide AnalysisAir AnalysisConclusionsReferencesRelated Abstract The conventional one-dimensional gas chromatography (1D-GC) compared to a comprehensive two-dimensional gas chromatography (GCÃâ€"GC) which provides the highest capacity, improved resolution and many of sensitivity. Additionally, it was create two-dimensional structure chromatogram, which is the proof of assistance in the composite class. Samples can often be minimized or even eliminated in some cases for the practice, as technology provides excellent separation power. All these benefits make GCÃâ€"GC in the toxic compounds involved in the determination of trace level environmental analysis of a very good tool in complex matrices. This paper summarizes some of the environmental analysis and review and monitoring of the GCÃâ€"GC applications Introduction Many years of humans society development led to many of the world distribution of chemicals in the atmosphere, the Earths surface and land border. Many of these compounds are harmful to the worlds ecosystems and the people. Analysis of these compounds in the environment is important. When analytes have high vapor pressure, gas chromatography is the selection method. The main problem in the environmental analysis is to analyze the existence of material is usually very complex matrix trace. Result, a huge research work into the analysis of major environmental pollutants [1]. Methods used in environmental analysis is usually the same as in all aspects of practice. It includes sampling, sample preparation, separation and detection. All of these steps may benefit from change, it is usually the biggest limitations imposed by the separation step. In gas chromatography (GC) cases, the majority of environmental samples containing analyte and matrix components of many closely eluting peaks in a chromatographic dimension (1D) the maximum total capacity is greatly exceeded, and many coelutions and unresolved in the separation region was observed. This led to the analyte of interest and quantify the poor separation [1]. Poor resolution in the chromatographic analysis of sample preparation and detection of high demand for equipment placement. Expensive and labor-intensive sample preparation, and solvent waste may cause a lot of harmful to the environment.   By microextraction method development, such as liquid-liquid microextraction (LLME) and solid phase microextraction (SPME) and non-dissolved sample introduction system (ie, direct thermal desorption), has the potential to greatly simplify the sample preparation process, without sacrificing sensitivity and selectivity [2-5]. On investigation, lack of resolution often means using mass spectrometry (MS), including high-resolution mass spectrometry (HRMS), in some cases, is necessary. Figure 1 illustrates the GC-MS encountered in the common problems [36]. In the analysis of food extracts commonly 1D-GC clinch with insecticides (Fig. 1b), trace interest (in this case chlorfenvinphos) coelute analyte and sample matrix is ​​more abundant components. Results obtained for such compounds, mass spectrometry (Figure 1e) frequently contains compounds derived from fragments of interference, leading to poor matching and library mass spectrometry (Fig. 1d). MS overlap algorithm may greatly improve the quality of the information of coeluting peak, but they are not always successful, when the number of coelutions is high. Figure 1a shows, full 2D-GC (GCÃâ€"GC) to increase space and improve the chromatographic separation of the resolution, resulting in the separation of analytes of interest (chlorfenvinphos) from coeluting compounds and matrix components. Result, improved the quality of the analyte mass (Fig. 1c), taking into account the proof of a more confident analysis of material (Figure 1d). It is possible that some coelutions exist; these may often solve efficiently overlap with the MS, leading to better results, while reducing the number of components when the coeluting. GCÃâ€"GC separation with the increased power res ulting in a successful demonstration and quantification of analytes. Fig. 1 GCÃâ€"GC–TOF MS versus 1D-GC–TOF MS for the analysis of a carrot extract. The highest-capacity problem in terms of conventional gas chromatography through multi-dimensional gas chromatography to cope (MDGC) implementation. In this method, one-dimensional (1D) chromatogram of a complex and unresolved part is subjected to the stationary phase coated with a second column separation of the other selectivity [1]. Although this method increases the 1D chromatographic part of the choice of chromatographic resolutions, this method with automation challenging, and only a few sample components can be adequately addressed. However, the many applications is good for the PCBs, pesticides and toxaphene analysis, among other things, the report with different degrees of success [6-12]. Overall, however, is the exact number of separation will be beneficial, if the entire sample is subjected to a separation in two dimensions. This became possible a comprehensive two-dimensional gas chromatography (GCÃâ€"GC) in the introduction. Principle for Two-Dimensional Gas Chromatography (GCÃâ€"GC) 2D-GC is a comprehensive method of fundamental solution to meet the highest capacity. A typical structure of GCÃâ€"GC set in Figure 2. The basic structure of GCÃâ€"GC using virtually is the same as the composition of 1D-GC. These include syringes, oven, columns and detectors. In a typical GCÃâ€"GC system, using non-polar stationary phase coated with a thick coating of a long column was installed as the main column. The exports through a special interface or modem is connected to the entrance of the second dimension column coated with stationary phase of another selectivity. Modulator connected not only to primary and secondary column; its main role is repeated trapping of the effluent fractions from the first dimension and periodic injection of them to the form of narrow pulses separated into further chromatographic analysis. Because the operation of 2D-GC in the fast condition, the detector in the GCÃâ€"GC selection is limited to those capable of fast data collection rate. For e xample, GCÃâ€"GC detector can include flame ionization detector (FID), electron capture detector (ECD), single atomic emission detector (AED), sulfur compounds optical detector (SCD), nitrogen photodetector compounds (NCD) and time of flight mass spectrometer (TOF MS). Fig. 2 A block diagram of a GCÃâ€"GC system. Modulator is the important part of the instrument, because it guarantees the separation is comprehensive and multidimensional [13]. In 1991, the first implementation of the GCÃâ€"GC, the field has witnessed a number of modulator design [14]. Initially, the use of thermal adjustment of the heat modulator was implemented; however, the modular cryogenic liquid (liquid carbon dioxide or nitrogen) is currently the main use. Modulator at low temperatures within the system, each design has its own distinct advantages and limitations, making it suitable for analysis of the specific type. For example, the analysis of water pollutants has been developed an interface [19], when the buildings, and an in-house applications modulator in the quantitative analysis of PAHs and PCBs has been described [15]. Then, the modulator of the different types of analyte in the analysis of organohalogenated been evaluated [16]. The implementation of GCÃâ€"GC provides the following advantage to surpass the 1D separation method: improvement separation strength; improved sensitivities; and constructs or highly predetermined, stratography spectrum. In the environment analysis, GCÃâ€"GC has the potential to improve the toxic compound through the separation from the coeluting analysis and the matrix component, increases the detection limit such chemical product and provides the ideal for the surveillance application the two-dimensional stratography spectrum which constructs. Finally, this possibly causes to reduce to the smallest sample preparation procedure, and reduces analysis time. Other applications are also possible. For example, recently, GCÃâ€"GC the product estimate which divided into for the diesel oil hydrocarbon environment had used, was important affected many ecosystems [17] the oil leak. Application of GCÃâ€"GC in Environmental Analysis Water and Sediment Analysis The water is the most basic material to the life in planet. In order to estimate that the tap water safety for human consumption, the rapid, precise and the accurate method needs to analysis the water. The sediment is also important for river and the lake; The analysis of water pollutant is time-consuming sample preparation, follows by GC-MS analyzes. In the initial period realized that GCÃâ€"GC has the great potential improvement to analysis water and sediment. In its earliest applications in this region, GCÃâ€"GC was explained possibly from the common matrix interference which is separating the BTEX (benzene, toluene, ethyl benzene and xylene) and methyl alcohol tert butyl ether (MTBE), when and SPME [18]. The separation strength of GCÃâ€"GC is improved; MTBE and the benzene are the foundation line solution in the 2nd chromatograph analysis space. This research showed GCÃâ€"GC has the great potential for water   pollutant analysis by combination this technology with microextraction (head space SPME). Certain Earths freshwater body is polluted daily by petroleum and the oil contamination. In the 1970s, it is pays attention the petroleum sample stratography spectrum to exhibit a model, has not solved, foundation line which rises â€Å"hillock† [20]. Chromatogram is the complex part, including compound many different kinds, refers to â€Å"unsolution complex mixture† at present [21]. GCÃâ€"GC-FID uses in analysis of two different freshwater sediments [21]. Observed the conventional sample preparation procedure, the author has used the superior resolution, and has constructed the chromatogram of sediment for UCM different levele by GCÃâ€"GC. The chromatogram obtained for two samples provides by clue direction contamination important source researcher. , The research showed GCÃâ€"GC the potential importantly in the environment law, for an environmental chemistry basic tool, environmental audit. The nonylphenol polyethylene ethoxides degenerated product, was possible feminine hormone splitter [22]. Increases the concern, NPs from the urban district [23] the water and the deposition present are found. GCÃâ€"GC-TOF MS is the NP isomer separation from technical mixture [24] used. 41 components are identified. Figure 3 explanation GCÃâ€"GC-TOF MS application to NP isomer respective ion trace analysis from identical research. Two NP stave products were explained that m/z 135 (chart 3a) and m/z 149 (chart 3b). Two chromatogram exhibition group type separation, emphasizes by the connection compound peak maximum value in the identical homologous family incline line. It from as a result of various NP isomer structure similarity, the complete separation is the very difficult this chart is obvious. However, other resolution strength by GCÃâ€"GC provided â€Å"cleanly† the mass spectrum to provide, made the analysis proof to be easier. Fig. 3. Extracted ion GCÃâ€"GC–TOF MS chromatograms of a technical nonylphenyl (NP) mixture GCÃâ€"GC for to the environment pollutants analysis was recently the application current in oceanic deposit [25]. A qualitative method has developed, fast and is unified according to the tendency by the ultrasonic wave assistances extraction to the complex samples high resolution analysis provides to GCÃâ€"GC-TOF UAE which is fast and high efficiency selective sampling pretreatment procedure is utilized solid sample [30]. A high efficiency and has the selective sample preparation method, when the powerful separation method GCÃâ€"GC combine with UAE can causes 1500 kind of more than several not aromatic hydrocarbon (PAHs) the compound and the certificate resolution, NPs and dialkylated benzene. Once more, GCÃâ€"GC not only ability from each other isolation analysis, and has proven from the sample matrix priceless. The carcinogen which and the mutagen suspected, PAHs is many industry activity by-product and the universal existence is distributed in the environment. Because it requests the hard sledding and has the selective sample preparation, they in the deposition samples trace determination are difficult. The improvement to complex matrixs PAHs, the Cavagnino trace analysis with GCÃâ€"GC-FID [large-volume splitless injection (LVSI) technology]. Sample complex which analyzes is many deposition sample representative who obtains from the river and the lake. Separated and investigates seven PAHs which diluted in the synthesis diesel oil to demonstrate the LVSI- GCÃâ€"GC-FID potential achievement in the low ppb level for to trace amount analysis one powerful and the rapid tool in complex matrix PAHs. While, Ong. and so on has developed a PAHs rapid surveillance method probably in the soil sample, utilizes liquid extraction (PLE) GCÃâ€"GC-FID [27]. The current publishing work is merely GCÃâ€"GC latent serviceable demonstration to deposition sample PAH analysis. In brief, with the resolution which improves, improvement many sensitivities and the stratography spectrum which orders, GCÃâ€"GC may add on the result which effective and the rapid sample preparation method produces cannot be achieved by the routine analysis procedure. Analysis of PCBs, PCDDs and PCDFs Polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and some polychlorinated biphenyl (PCB) congeners is dominated by bioaccumulation and biomagnification in the environment and thus is a dangerous The wildlife and people. Many are suspected carcinogens and induced changes of [28]. Of PCBs, dioxins and furans in the environment assessment of certain requirements of a method to isolate and quantify them in complex samples such as food, soil and water. GCÃâ€"GC provides one advantageous method in complex matrixs PCDDs and the PCDFs analysis. In its one of early experiments, a liquid crystal main column and a limitless secondary column (according to steam pressure separation) uses in (according to the planarity separation) separates the tone and from technical mixture [30] non-straight PCB congeners. The connection GCÃâ€"GC microelectron captures investigates (MECD) is toxic PCBs, PCDDs and the PCDFs determination is the application in the cod liver sample [29]. The analysis result showed all 12 priority PCB from liver sample congeners, and most toxic Dai Aoxin and fu nan the full separation and the proof nail fast with 90 PCBs and 17 contain poison PCDDs and PCDFs. Moreover, when compares with the standard sample preparation procedure, the liver sample pretreatment does not have the selectivity and reduces to is smallest. It has included the direct injection and fractionation followed cell degree of illness gradually draws back, the centrifuge process to enter GCÃâ€"GC the system. Figure 4 showing from the 2nd stratography spectrum which obtains to the cod liver samples analysis. Recently, an item of multilaboratory research has been conducted in food sample, analyzes PCDD/Fs and World Health Organization PCBs through once more GCÃâ€"GC-MECD and the GC-HRMS comparison and the explanation GCÃâ€"GC great potential in the rapid surveillance application [31]. With the standard analysis method comparison GCÃâ€"GC, GCÃâ€"GC the performance is unified (GCÃâ€"GC-ID-TOF MS) has to 13C mark isotopic dilution (ID) TOF MS conventional GC-HRMS to appraise [32]. Quantification 17 PCDD/Fs and four PCBs nail fast in the soil and in the deposition sample are two methods are comparable. However, GCÃâ€"GC implementation request only smallest sample preparation, and causes the signal improvement (factor 5-10), superior resolution, lower instrumentation expense, and improved TOF the MS data [32] the ghost overlaps legitimately. As highest capacity which and resolution result increases, the unknown compounds proof is possible. Fig. 4 GCÃâ€"GC–ECD chromatogram of a cod liver sample spiked with 90 PCBs [29]. Pesticide Analysis Forms the challenge to the pesticide analysis to analyze the chemist to prepare about the sample to make the law and the chromatography. Is similar other toxic compound, the pesticide is usually distributed in the trace amount environment. Moreover, they are extreme complex matrix part of for example foods, the soil and the water sample. Needs to be like today presses to the rapid high resolution analysis method. GCÃâ€"GC the application early showed the method potential regular implementation to the pesticide analysis in persons organization in the future. Supercritical invariable extraction (SFE) with GCÃâ€"GC-FID together utilizes the analysis in persons blood serum [33] the pesticide. To were few from the sharp persons blood serum extractions 15 pesticides foundation line segments achieve in four minutes. Later, GCÃâ€"GC-FID to estimate that the child pesticide exposure has been utilized through the use urine and the blood serum [34] low-power. This special example in were few showed 16 pesticide complete separations in four minutes. Recently, has been demonstrated including PCBs and the organic chlorine pesticide 59 organization pollutants proof and the quantification [35]. But GCÃâ€"GC-ID-TOF MS completed the comparable result author who ran in standard routine analysis (GC-ID-TOFMS) to indicate that analyzed like this, three different injection needs. GCÃâ€"GC the application earl y showed the method potential regular implementation to the pesticide analysis in persons organization in the future. Supercritical invariable extraction (SFE) with GCÃâ€"GC-FID together utilizes the analysis in persons blood serum [33]. Pesticide determination in food extract is similarly important. Separated using GCÃâ€"GC-TOF MS and identifies 58 pesticides to nail fast completely on the vegetable was explained [36]. This completed with has been smallest and the non-selective sample preparation: The celery or the carrot sample and the sodium acetate and the ethyl acetate have chopped, mixed, was mixed, has been separated, and is dried. The extract is injected entered GCÃâ€"GC [36]. Recently, separated 12 halogenate compound kind of groups five different GCÃâ€"GC column combination to appraise, including PCBs, PCDDs, PCDFs, multi-chlorobenzene diphenyl ester (PCDEs), multi-chlorobenzene naphthalene (PCNs), multi-chlorobenzene dibenzothiophenes (PCDTs), multi-chlorobenzene terphenyl (PCTs), multi-chlorobenzene alkane (PCAs), toxaphene, multi-bromination biphenyl (PBBs), multi-bromination diphenyl ether (PBDEs) and organic chlorine pesticide (OCPs) [37]. Although this article focal point is the different compound kind of major group separates, was also explained in the family separation. When the separation and proof all 28 OCPs are pure pesticide mixture has only been demonstrated that majority has been separated fully, since, when injects along other 11 compound kind of [37]. Therefore, its as if that the column establishment which disposes appropriately with one, GCÃâ€"GC may use takes mainly shields step for the environment sample contamination and along pol lutant many other kind of pesticides, with smallest sample preparation. Air Analysis Volatile organic compound (VOCs) in metropolis photochemical smog [38] the generation plays a strong character. The World Health Organization thought that possibly has to the air granular materials exposition to the human health [39] the ill effect. But, uncertainty existence about from VOCs health effect in metropolis granular material (PM) [40]. Therefore, requests rapid, reliable and information method guarantee in air pollutant successful surveillance, proof and discovery. Many PAHs and PAHs (oxy-PAHs) which oxidizes is the carcinogen which and the mutagen suspected, with, therefore they are in the metropolis aerosol analysis profitable target analysis. GCÃâ€"GC-FID and GCÃâ€"GC four-pole MS (QMS) is applied permits from Finland about 1500 peaks goal PAHs [41] investigates in the metropolis air sample and the proof. But woman is unified the method for the compound proof and the quantification, used GCÃâ€"GC-FID the combination to confirm the good reproducibility. 13 non-goal PAHs has been identified, and ten goal PAHs by quota. Found PAH centralism scope (0.5-5.5 ng/m3) with in Europe [41] other parts of standard methods obtained the result was comparable. The cigarette smoke is estimate extreme complex mixture component [43] which has not recognized including about 4,700 kind of identifications compound and 100,000. GCÃâ€"GC-TOFMS utilizes the solution approximately from the cigarette smoke [43] 30,000 peaks. After this, analyzes cigarette smoke condensate simpler sample determination neutrality score [44], basic score [45] and acidic score [46] chemical composition. Conventional GC-MS possible to separate 200 unknown peaks and identifies 115 hydrocarbons from the cigarette condensate limitless neutral scores; To identical sample GCÃâ€"GC analysis, however, has achieved 4,000 kind of compound separations and 1,800 hydrocarbons [44] proved. In another research, GCÃâ€"GC-TOF has identified 377 kind of nitrogen-containing compound to the cigarette condensates basic scores MS analysis, in 155 is the pyridine derivative, 104 kinds kui lin or different kui lin derivative and 56 kind of pyrazine derivative [45]. Conclusions GCÃâ€"GC has achieved the condition rapidly for to the volatile organic compound analysis most powerful tool. It appoints oneself achievement to be suitable completely for in the complex sample surveillance analysis technology. In the environment analyzed area, this includes PCBs by the analysis many example testimony to the common environment pollutant, PCDDs, PCDFs, PAHs and the pesticide in the complex environment matrix. Moreover, GCÃâ€"GC has the potential to simplify the sample preparation procedure (even completely to eliminate them), when simultaneously causes when the shorter overall analysis time high resolution stratography spectrum. Regarding widely a new analysis method which adopts, not only it is certainly reliable and renewable, but it should also exhibit the significant advantage to surpass the method which accepts. The example reported the showing GCÃâ€"GC method advantage in this review in the traditional 1DGC separation. In GCÃâ€"GC historical first years period, the instrumentation development is the main focal point; However, from GCÃâ€"GC systems commercialization, the application quantity which reported greatly increases in the environment analysis and other scientific fields. Therefore, we may anticipate that the transition automation GCÃâ€"GC is unified on-line sample which the correspondence uses to prepare gradually the equipment in the regular environmental monitoring.
