Abstract

A sensor system based on quartz thickness shear mode resonators is developed for the detection of organic pollutants in pure water, drinking water, and sea water. Unpolar polymer coatings with a glass transition below operating temperature and calix[8]arenes have been found as most sensitive, reversible and reliable for working in an aqueous environment. Mass changes and changes in viscoelastic properties of the coating caused by analyte sorption contribute to the sensor response.
