Abstract A resonant-cavity based microwave differential technique has been developed for the detection of humidity in a gas in the low-ppm range. The determination of the contaminant content is related to the shift in the resonant frequency of a measuring cavity compared to a reference cavity. Preliminary measurements carried out on binary mixtures of nitrogen-sulfur hexafluoride (SF/sub 6/) and nitrogen-water indicates a detection threshold below 10 ppm, which compares well with theoretical predictions.
