Simultaneous detection of benzene and toluene using a pulsed ion mobility spectrometer.

Highlights: [•] Detection of low concentration of benzene in ion mobility spectrometry with non-radioactive and non-optical source. [•] Improved investigation of simultaneous detection of benzene and toluene possible with this source. [•] Less signal reduction when adding toluene to benzene achieved. [•] Important example for ionization control in IMS with pulsed electron sources via electron beam intensity and duration. [ABSTRACT FROM AUTHOR]
