    GC–MS is used for the analysis of unknown organic compound mixtures. One critical use of this technology is the use of GC–MS to determine the composition of bio-oils processed from raw biomass. [29] GC–MS is also utilized in the identification of continuous phase component in a smart material, magnetorheological (MR) fluid. [30]

  4. Gas chromatography - Wikipedia

    en.wikipedia.org/wiki/Gas_chromatography

    Mass spectrometer (MS), also called GC-MS; highly effective and sensitive, even in a small quantity of sample. This detector can be used to identify the analytes in chromatograms by their mass spectrum. [14] Some GC-MS are connected to an NMR spectrometer which acts as a backup detector. This combination is known as GC-MS-NMR.

  5. Two-dimensional chromatography - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_chromatography

    Gas chromatography-mass spectrometry (GC-MS) is a two-dimensional chromatography technique that combines the separation technique of gas chromatography with the identification technique of mass spectrometry. GC-MS is the single most important analytical tool for the analysis of volatile and semi-volatile organic compounds in complex mixtures. [7]
