gas chromatography coupled with mass spectrometry
Headspace Solid-Phase Microextraction Coupled with Gas Chromatography–Mass Spectrometry for the Characterization of Polymeric Materials. Jan 01, 2018. It has been routinely used in combination with gas chromatography (GC) and GC–mass spectrometry (GC–MS) and successfully applied to a wide variety of compounds, especially for the
One of the most useful separations and detection instrument in metabolomics is gas chromatography coupled with a mass spectrometer (GC/MS). This platform is known for its ability to give a very good result and robustness on analysis of esters, fatty acids, alcohols, aldehydes, terpenes, and so on (12) .

Liquid chromatography–mass spectrometry (LC-MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). Coupled chromatography – MS systems are popular in chemical analysis because the individual capabilities of each technique are enhanced synergistically.
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.
Gas Chromatography Mass Spectrometry analysis can be performed on liquids, gases or solids. For liquids and gases the sample is commonly directly injected into the GC. For solids, the analysis is carried out by solvent extraction, outgassing (desorption) or pyrolysis.
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.
Gas Chromatography mass spectrometry is the workhorse of the organic environmental laboratory. This is the instrument you will use for methods such as 524.2 , 624 , 8260 volatiles, and 525 , 625 , and 8270 semi-volatiles.
