Analysis of trimethyl carboxyphosphate samples by gas chromatography-mass spectrometry, using typical conditions resulted in significant decomposition of the analyte. Optimization of injection conditions, including conditioning of the injection port liner, produced a dramatic increase in observed peak areas and afforded an effective method for detection of trimethyl carboxyphosphate at the <1 microg mL(-1) level.
