PY-GCMS (Pyrolysis-Gas Chromatography-Mass Spectrometry): A Comprehensive Analysis of Principles, Advantages and Applications

PY-GCMS (Pyrolysis-Gas Chromatography-Mass Spectrometry) is a core technology for analyzing non-volatile, high-boiling-point, cross-linked, or macromolecular samples. It overcomes the limitation that traditional chromatography cannot directly analyze non-volatile samples. Through the combined logic of "pyrolysis conversion → chromatographic separation → mass spectrometry identification", it enables the complete interpretation of information from samples to their components.
