Abstract
A methodology, based on gas chromatography/high resolution mass spectr ometry selected ion monitoring (GC/HRMS SIM) has been developed for th e determination of 3,3',4,4'-tetrachloro-azobenzene (TCAB), a potentia l carcinogen, in water. As internal standard we prepared [C-13(12)] la belled TCAB, from [C-13(6)] labelled benzene. TCAB was extracted from water by hexane followed by a cleanup column chromatography over basic alumina. Recoveries of TCAB range from 80.0 - 88.3%. The detection li mit of TCAB is about 50 fg of TCAB or 5 ppq in 1,000 mL of water.
