Abstract
The present disclosure relates to a process for facilitating the identification of target chemicals which may be detected by means of an ion mobility spectrometer and a system for implementing the same. In an aspect of the disclosure, there is provided a process for determining the ratio of CI″ to CI″.OOH reactant ion species formed in a pentachloroethane doped ion mobility spectrometer operating in negative mode, said process comprising: i) introducing a sample comprising or consisting essentially of isoflurane into a pentachloroethane doped ion mobility spectrometer; ii) collecting data relevant to the detection of two isoflurane monomer ions formed following reaction with CI″ and CI″.OOH reactant ion species present in the pentachloroethane doped ion mobility spectrometer; and iii) determining the ratio of CI″ to CI″.OOH reactant ion species formed in the pentachloroethane doped ion mobility spectrometer based on an evaluation of the data collected.
