Analysis of Residual Solvent in Polymers by GC/MS

Introduction

Pyrolysis gas chromatograph mass spectrometers (Py-GC/MS) are commonly used for polymer analyses. The combination of a temperature controllable double-shot pyrolyzer (PY-2020D:Frontier Lab Ltd.) and a gas chromatograph mass spectrometer (GCMS-QP5050A) enables simple analyses of polymers, as well as residual solvents and additives in polymers by various methods including the EGA (evolved gas analysis) method and double-shot analysis (multiple-stage pyrolysis) method. This article demonstrates two analyses of residual solvents in polymers. Part 1 is an example of quantification of residual solvents in a polymer sample using a liquid sample injection unit (an accessory of the main unit). Part 2 is an example of EGA analysis to grasp the changes in residual solvents due to thermal processing on the polymer sample.
