Analysis of impurities in diethylene glycol using msFineAnalysis AI
Introduction
Diethylene glycol is a colorless and viscous liquid, and it is used as a raw material for a wide variety of chemicals including polyesters and antifreeze solutions. In our previous report MSTips No.043, we analyzed impurities in ethylene glycol compounds using the JMS-T100GC "AccuTOF™ GC". But because the substances were library-search unregistered (=unknown substances), the compositional formula could be suggested, but the structural formula was unknown and had to be derived manually. Qualitative analysis of trace constituents is expected to be achieved by combining highly sensitive measurements with the JMS-T2000GC AccuTOF™ GC-Alpha GC and the unknown substance structure analysis software msFineAnalysis AI. This MSTips presents the results of EI/FI measurements of diethylene glycol on a JMS-T2000GC AccuTOF™ GC-Alpha and qualitative analysis using msFineAnalysis AI.
