GC/MS: Gas Chromatography-Mass Spectrometry

One method to obtain the temperature profile of gases generated during sample heating is the EGA-MS method. However, this method introduces the generated gases into the mass spectrometer as a mixture without passing through a GC column, making it difficult to identify the compounds. In such cases, by trapping the gases once and performing GC/MS measurements using the heart-cut EGA method, it becomes possible to separate and identify the compounds. This example presents a case where polyvinyl acetate was measured using the heart-cut EGA method, revealing differences in the decomposition mechanisms depending on the heating temperature.
