      GC-MS based metabolome studies aim for the complete identification and relative or absolute quantification of metabolites in complex extracts from a large diversity of biological materials. Cited by: Gas chromatography-mass spectrometry (GC-MS) is a method that combines the features of gas-liquid 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. GC/MS.

    There are many uses of GC-MS in the QC/QA activities required for environmental investigations. Emphasis here is given to the bench-level QC steps needed to achieve acceptable accuracy and Cited by: 3. The technician has access to both the retention times and mass spectral data. Many scientists consider GC/MS analysis as a tool for conclusive proof of identity. GC/MS analysis, where the effluent to the .

    In metabolomics, the objective is to identify differences in metabolite profiles between samples. A widely used tool in metabolomics investigations is gas chromatography−mass spectrometry (GC/MS). More than compounds can be detected in a single analysis, if overlapping GC/MS . In a recent overview, Yolanda Picó highlighted the role of mass spectrometry (MS) for the food industry. As with her section on section on LCMS, the author created a comprehensive table comprising the .
