Rapid on-site determination of chlorobenzene in water samples using ion mobility spectrometry

A fast screening procedure for water samples contaminated with chlorobenzen e was developed. The volatile organic compounds were purged from water samp les and their concentration was determined with ion mobility spectrometry ( IMS) using corona discharge (CD) ionization. This analytical procedure perm its the determination of chlorobenzene with a concentration range of 3-30 m g/l. The analytical results are available within 5 min. In order to test th e general suitability of the method developed, the influence of sample matr ix, especially of accompanying chlorinated aromatics, on ion mobility spect ra of chlorobenzene was investigated.
