GC-MS Applications: Analysis of additives in plastic by thermal desorption (TD) GC-TOFMS: accurate mass measurement and isotope pattern matching

  • Summary

MS Tips No.138

Among various methods for characterizing plastics, qualitative and quantitative analyses using pyrolysis (Py) GC/MS and thermal desorption (TD) GC/MS are widely used. These are simple techniques, but provide detailed information. In this application note, we report the analysis of additives in plastic by thermal desorption GC-TOFMS using a thermal desorption system and JEOL JMS-T100GCV “AccuTOF™ GCv” GC-TOFMS. Identification of the analytes was accomplished by library search and accurate mass measurement. Isotope cluster pattern matching was performed using the software “Mass Spec Tools.”
