Abstract :
In this work, the performances of a Cr-doped WO3 sensor array are investigated for the application of this device as detector in gas chromatographic systems. Chromatographic separation modules combined with detectors based on semiconducting metal oxides enable the implementation of systems with both high selectivity and high sensitivity. Comparison of results of the sensor array and mass spectrometer detectors validates the use of this class of devices for low-cost systems for the determination of the volatile organic compounds contents in wines for quality assessment of alcoholic beverages.
