Experimental research on benzene detection using ion mobility spectrometer with a laser ionization source

Abstract:

An ion mobility spectrometer equipped with a laser ionization source is used for the sensitive detection of benzene. Mobility spectra of the benzene are presented. We also discussed the mobility spectra at various concentrations and drift voltages. Detection limits are determined to be in the upper ppbv range. In the end,the advantages and possibilities of this technique are briefly discussed.
