Generation Of Polluted Atmospheres For The Calibration Of Qcm Gas Sensors
26TH EUROPEAN CONFERENCE ON SOLID-STATE TRANSDUCERS, EUROSENSOR 2012(2012)
摘要
One of the major requirements for developing sensitive and selective detectors based on chemical gas sensors is to generate calibrated polluted atmospheres. In this paper a generation method of volatile organic compounds and explosive vapours is presented. The work was focused on the generation of 4-nitrotoluene (NT), 2,4 and 2,6 dinitrotoluene (DNT), 2,4,6-trinitrotoluene (TNT), toluene and nitromethane vapours. The methodology described in this study was applied to determine the detection limit of a Quartz Crystal Microbalance (QCM)-based sensor.
