Optimization of High-speed GC/TOFMS for Method TO44 Analysis

摘要

A fast GCMS system (FGCMS) consisting of a high-speed gas chromatograph equipped with a narrow bandwidth injection accessory and a time-of-flight mass spectrometer detector is being optimized for analysis of Method TO- 14 target compounds. The system consists entirely of commercially-available components. Turn-around time between sample injections has been reduced to six minutes, in contrast to an hour for conventional Method TO-14. Instrument configuration, control, and data processing procedures under development are described.
