Structural analysis of contaminant in polypropylene product using msFineAnalysis AI
Introduction
Polypropylene has high strength, heat resistance, and excellent workability, so it is used in many industrial products. In the process of productization, material pellets are pulverized, mixed, and molded. Contaminants mixed in these processes causes deterioration in product performance. Pyrolysis-GC-MS method is generally used to identify contaminants, but most of pyrolysis products are not registered in the mass spectra library. So it is difficult to obtain satisfactory results with qualitative analysis relying on library searches. Time-of-flight mass spectrometer JMS-T2000GC and unknown compounds structure analysis software msFineAnalysis AI are effective for qualitative analysis of these unregistered compounds (=unknown compounds). Previous report MSTips No.330 introduced molecular formula derivation by EI/SI integrated analysis for contaminant in polypropylene product. This MSTips introduces structural formula derivation by AI structural analysis.
