ABSTRACT:
A method and apparatus for detecting the presence of a vapor of an alkyl ester of phosphoric acid, particularly tributylphosphate, in ambient air. A sample of ambient air is heated to convert any alkyl ester of phosphoric acid to an alkene. The heated sample of air is then passed to a sample loop. Carrier air periodically carries a fixed volume of sample from the sample loop through a chromatographic column to a photoionization detector which detects the presence and amount of the alkene in the sample.
