Abstract:
Thermal desorption and pyrolysis (TD/PY) is a valuable method for materials analysis with gas chromatography and mass spectrometry (GC-MS). Polymers are identified by their pyrograms and pyrolysis products. 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 (chemical ionization, photoionization, and field ionization) are essential tools for the identification of unknowns in these complex mixtures. Taking a completely different perspective, soft ionization and pyrolysis with a deactivated fused silica column shows high-molecular-weight pyrolysis products that are not detectable by GC-MS or GCxGC-MS
