The Simple Monitoring method of Trichloroethylene Using a Quartz Crystal Microbalance by the Hybrid type

A highly sensitive method for the detection of trichloroethylene (TCE) using a quartz crystal microbalance (QCM) is described. This method (hybrid type QCM) uses lead dioxide and sulfuric acid as oxidizing agents to convert TCE into hydrogen chloride, which in turn reacts directly with a copper electrode on the quartz crystal surface. The results indicate that the sensitivity increases at higher temperatures. Using a calibration curve, it is possible to obtain a TCE gas concentration. This hybrid type QCM method allows for the measurement of very low concentrations of TCE, and has a detection limit comparable to the Japanese Environmental Standard (0.2 mg/m³)
