[Analysis Case] Analysis of Evolved Gases during High-Temperature Heating in Air by Pyrolysis GC/MS
It is possible to track the thermal decomposition behavior in the presence of oxygen.
The decomposition behavior of materials when heated in a vacuum or in inert gases such as nitrogen can differ from that when heated in air. Therefore, when conducting gas emission analysis, it is desirable to heat the materials in an environment that closely resembles the actual conditions to which they are exposed. In this case, a comparison of the gases emitted during the pyrolysis of polystyrene at 550°C in helium and in air was conducted. Only hydrocarbon compounds were detected in helium, whereas reaction products with oxygen, such as benzaldehyde, were also detected in air.
