Protocol DOI: Gas chromatography GC is the most widely used analysis for determining the structural distribution and quantification of hydrocarbons in complex mixtures. A sample dissolved in a solvent is vaporized and carried by a gas phase, usually helium or. A sample dissolved in a solvent is vaporized and carried by a gas phase, usually helium or hydrogen, allowing individual components to separate as they interact with a thin-film coating of stationary phase, typically a chemically bonded polymer attached to the inner walls of a capillary column. Several standard industry and government-issued environmental methods are listed, and specific protocols for various hydrocarbon analyses are discussed. Antibody Data Search Beta.

Handbook of GC-MS

From reviews of the prior edition: "The present English version is more than just a handbook which means a comprehensive and instructive book on the subject. Raddatz, European Food Research and Technology The book is a detailed overview on the fundamentals, developments, 'The book is a detailed overview on the fundamentals, developments, and applications in the various fields of GC-MS. He started his career in diagnostics and medical analytical instruments before working for a number of German companies in gas chromatography and mass spectrometry. Hans very recently joined CTC Analytics AG, a privately owned Swiss company, supporting and developing front-end automation in gas and liquid chromatography for innovative sample preparation solutions.

Gas chromatography—mass spectrometry GC-MS is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. GC-MS can also be used in airport security to detect substances in luggage or on human beings. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated beyond identification. Like liquid chromatography—mass spectrometry , it allows analysis and detection even of tiny amounts of a substance. A nonspecific test merely indicates that any of several in a category of substances is present. Although a nonspecific test could statistically suggest the identity of the substance, this could lead to false positive identification.

With a development of the metabolomics field, complementary cross-platform approaches started to attract attention, as none of the contemporary analytical methods had the capacity to cover the entire space of the human metabolome. In the current manuscript, we have evaluated an online coupling of gas chromatography GC -mass spectrometry MS and flame ionization detector FID as ways of cross-detector analysis. The possible value of this combination was recognized from the very first days of GC-MS history but was never explored in detail. We have compared the basic analytical parameters of both detectors, such as limit of detection LOD and limit of quantification, with intra- and interday reproducibility. At the same time, FID appeared to be more robust, showing lower relative standard deviations RSDs for intra- and interday reproducibility. We conclude that the gain of this dual detector acquisition appears to be most evident for complex biological samples, where wide dynamic range and predictable response of FID are useful for an initial quantitative overview of sample composition and estimation of molar proportions of different metabolites.
