A simple analytical method for the determination of trichloroethylene (TCE) in soil and groundwater using a lipid-coated quartz crystal microbalance (QCM) sensor was developed. For the measurement of the groundwater, shaking a water sample by hand in a sealed-bottle attained concentration equilibrium of TCE between water and headspace gas in the bottle. The frequency change of the QCM sensor that was monitored after inserting it into the headspace of the sealed bottle was turned out to be proportional to the concentration in water. Comparison of analytical performance of the QCM sensor and that of the gas detector tube, conventionally used for monitoring of these gases, was carried out. The former method gave a wider dynamic range of the measurement.
