Determination of Organobromine Compounds in Water by Gas Chromatography-Negative Ion Chemical Ionization Mass Spectrometry

Gas chromatography-negative ion chemical ionization mass spectrometry (GC-NCIMS) was evaluated as a method for qualitative and quantitative determination of organobromine compounds in water. The negative ion mass spectra of bromine containing trihalomethanes (CHBrCl2, CHBr2Cl and CHBr3) consisted of two peaks of m/z 79 and 81, corresponding to mass numbers of bromine atom. The detection limit for these compounds was 1.0 ppb. The results in this study showed that organobromine compounds in water could be assayed by GC-NCIMS.
