Abstract:
1. A method for determination of chloroethers in a sample, comprising: directly contacting an SPME fiber with an aqueous sample to form an enriched SPME sample, wherein the aqueous sample comprises one or more chloroethers selected from the group consisting of bis(2-chloroethyl)ether, bis(2-chloroisopropyl)ether, and bis(2-chloroethoxy)methane, and the contacting is carried out with a single pass of a flowing stream of the aqueous sample; and desorbing the chloroethers from the enriched SPME sample and determining the content of the chloroethers in the sample with a flow assisted-solid phase microextraction/gas chromatography-mass spectrometry (FA-SPME/GC-MS) system comprising wherein the desorbing is carried out inside the sample port of the gas chromatograph to obtain a desorbed analyte composition and the desorbed analyte composition is chromatographed in the gas chromatograph.
