The sensitivity of our proton-transfer reaction mass spectrometer system has been improved by nearly two orders of magnitude, so that now on-line monitoring of volatile organic compounds at levels of a few pptv is possible. This has been demonstrated by means of calibration data down to 200 pptv and
## Abstract An instrument has been developed and tested for the continuous measurement of volatile organic compounds (VOC) in air. The system consists of a gas chromatograph equipped with a dedicated sampling device that allows the sample to be transferred to a cooled microtrap via sampling loops (
