Abstract
A highly selective pyrolysis-gas chromatography-tandem mass spectrometry (Py-GC-MS-MS) procedure for the quantitative determination of high molecular weight (MW > 1000) chlorolignosulfonic acids in river and drinking water is presented. The use of MS-MS considerably enhanced the selectivity toward 2- methoxy-5-chlorophenol (5-chloroguaiacol; a highly characteristic pyrolysis product of chlorolignosulfonic acids) as compared to SIM conditions. The dissociation of the parent ion at m/z 143 (C
