Detection and estimation of bis(chloromethyl)ether in air by gas chromatography-high resolution mass spectrometry
摘要：
There is mounting evidence that bls(chloromethyl)ether (BCME), which is reported to form spontaneously from the two common materials formaldehyde and HCl, is a carcinogen. A method is presented, which uses adsorption and then combined gas chromatography-high resolution mass spectrometry to detect the presence of BCME in air reliably and with a very high degree of specificity. The method involves "mass fragmentographic" monitoring of the ion m/e 78.9950 (C2H4OCl+) from BCME and is shown to be applicable down to levels of 0.1 ppb v/v BCME on a 1-1. air sample or 0.01 ppb v/v BCME If a 10-1. air sample is taken.
