Pyrolysis–gas chromatography–mass spectrometry
Pyrolysis–gas chromatography–mass spectrometry is a method of chemical analysis in which the sample is heated to decomposition to produce smaller molecules that are separated by gas chromatography and detected using mass spectrometry. == How it works == Pyrolysis is the thermal decomposition of materials in an inert atmosphere or a vacuum.
