An HPLC procedure has been developed for the determination of chloroacetyl chloride (CAC) in air. CAC is collected on Tenax-GC coated with 9-((N-methylamino)methyl)anthracene (MAMA) packed in glass tubes. The MAMA acts as an in situ derivatizing agent for CAC, and the resulting amide is solvent desorbed from the Tenax support and analyzed by HPLC with fluorescence detection. Standard vapor concentrations of CAC were generated in silanized glass for laboratory validation in the range of 5-2500 ppb CAC based on a 5-L air sample. The average recovery was 79% with a pooled relative standard deviation of 0.083. Up to 100 L of air was sampled and similar recoveries were obtained implying a practical limit of quantification 1 ppb. The limit of detection for the MAMA derivative of CAC, N-(9-anthracenylmethyl)-2-chloro-N-methylacetamide, under optimal conditions is less than 1 pg. 12 references, 1 figure, 2 tables.
