In a typical thermal decomposition GCMS, samples are heated to detect volatile components; however, analyzing components that do not volatilize upon heating or those with low detection sensitivity is challenging. Therefore, by adding a special reagent to the sample and heating it, it becomes possible to detect substances that are usually difficult to identify. For example, in the analysis of polymers, thermal decomposition of the polymer results in the detection of a large number of decomposition products, and in some cases, peaks may overlap with other additives, making analysis difficult. However, by performing reactive thermal decomposition GCMS, it is possible to detect the methyl esters of monomers and to separate and analyze them from the additives. Thus, even when the target analytes are difficult to detect using conventional analysis, reactive thermal decomposition GCMS allows for sensitive detection by selecting appropriate reagents for the analytes.
