Abstract
The method of piezoelectric quartz crystal microweighing was used for proximate analysis of toluene-containing gases. As a detector was used a commercial quartz resonator. The toluene detection limits were impr oved by modifying the detector electrodes with active phases (polyethy lene glycols). The optimal conditions were determined for preparing so rbent films and obtaining the maximum analytical signal.
