The sulfur mustard (SM) vapor sensitive property of polyepichlorohydrin (PECH) polymer coating was investigated by using quartz crystal microbalance (QCM) sensor. The measurements were based on the frequency shifts (Hz) due to the sorption of SM vapor in the polymer coating of the modified QCM. The response of QCM sensor was found to be about 410 Hz for SM vapors. The influences of coating thickness and temperature on the sensor response were examined. The sensor showed optimum response and reversibility at 4 KHz of coating thickness and lower temperature. The relevant detection parameters like sensitivity, reversibility and reproducibility were evaluated for SM detection.

The sensor showed optimum response and reversibility at 4 KHz of coating thickness and lower temperature. The relevant detection parameters like sensitivity, reversibility and reproducibility were evaluated for SM detection.
