Automated SPE and Fast GC-ECD Analysis of PCBs in Waste Oil

Abstract

A fast SPE-GC-ECD method for the analysis of PCBs in waste oil was developed. A complete profile was obtained following SPE with a 12 minute GC run-time using a low thermal mass column heater (LTM). Full automation of the sample preparation and analysis (except sample weigh-in) enables a daily throughput of 100 samples. A wide range of concentrations can be determined using a dedicated column and Electron Capture Detection (ECD).
