Abstract:
Thermal desorption and pyrolysis (TD/PY) is a sample introduction method for materials analysis with GC-MS. However, pyrolysis produces much more complex mixtures than can be separated by one-dimensional gas chromatography alone! GCxGC-MS is a useful approach to monitor pyrolysis reactions on a small scale and characterize the products of pilot-plant pyrolysis. High-resolution mass spectrometry and soft ionization methods are essential tools for the identification of unknowns in these complex mixtures. On the other hand, soft ionization and pyrolysis with a deactivated fused silica column with _no_ GC separation shows high-molecular-weight pyrolysis products that are not detectable by GC-MS or GCxGC-MS.
