Abstract
A new generation of ion mobility spectrometers has been designed espec ially for the environmental monitoring due to toxic compounds in ambie nt air: phosgene, halocarbons, isofluorane, halothane, formaldehyde, e thylenoxide, acrolein, chemical warfares and many others. The IMS is e quipped by means of tritium ionization sources, which have lower radia tion hazards than nickel-63 sources. Aromatics are monitored by means of a special version using photoionization. Minimal detectable concent rations are in the ppb-range. mostly even below.
