Gc ms

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. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples, including that of material samples obtained. Thermo Scientific gas chromatography mass spectrometry systems provide complete solutions to the most challenging applications. Combined with productivity enhancing software, our advanced GC-MS instruments empower you to meet your application's most stringent requirements for performance, reliability, and value GC/MS begins with the gas chromatograph, where the sample is volatized. This effectively vaporizes the sample (the gas phase) and separates its various components using a capillary column packed with a stationary (solid) phase. The compounds are propelled by an inert carrier gas such as argon, helium or nitrogen GC-MS is a hyphenated technique that combines the two methods of gas chromatography (GC) and mass spectrometry (MS). As discussed above, GC uses a capillary column to separate constituents in the sample by forcing a mobile phase containing the sample mixture through the length of the column containing the stationary phase GC-FID eller GC-MS. Vid analys av grupper av föreningar (t.ex. oljor) finns däremot inte någon halt som är en absolut sanning eftersom halten olja kan definieras på olika sätt. Vid analys med GC-FID relateras halten olja till signalen av en referensolja. Referensoljan motsvarar en blandning av dieselolja och en tyngre olja
