Pyrolysis gas chromatography mass spectrometry (abbreviated as Pyr-GC/MS) is a method of chemical analysis. In Pyr-GC/MS, the sample is decomposed by heating at high temperatures under an inert atmosphere or under vacuum to produce smaller molecules that are separated by gas chromatography and detected using a mass spectrometer. Pyr-GC/MS is widely used to characterize polymers and complex organic molecules such as tholins.
