PyGCMS Testing - Pyrolysis Chromatography-Mass Spectrometry Analysis Services - Shanghai Jituo Technology

Shanghai Jituo Technology provides Py-GCMS (pyrolysis chromatography-mass spectrometry) testing services. Pyrolysis chromatography-mass spectrometry testing is used for component analysis and formulation cracking of polymer materials, rubber, various fibers, and coatings.

Pyrolysis chromatography is an effective analytical technique that decomposes non-volatile molecules into fragments suitable for chromatographic analysis by heating, thus generating a reproducible characteristic fingerprint of non-volatile samples. This technique can be applied in many different fields.

Instrument Model and Parameters
