Impact/Purpose:
This project is intended to provide the Agency with much faster methods of GCMS analysis without sacrificing data quality.
Description:
A high speed GC/MS system consisting of a gas chromatograph equipped with a narrow bandwidth injection accessory and using a time-of-flight mass spectrometer detector has been adapted for analysis of ambient whole air samples which have been collected in passivated canisters. Commercially-available system components were used throughout. Turn-around time has been reduced by a factor of ten compared with EPA Method TO-14, and data are processed concurrently with sample analysis. Detection limits compared for both methods. Instrument configuration and control are described. Data from samples analyzed by both high speed GC/MS and Method TO-14 are compared.
