Development of environmental monitoring sensor using quartz crystal micro-balance

Abstract

A quartz crystal microbalance (QCM) sensor system for the detection of odorants, especially environmental pollutant, was constructed by depositing various phospholipids, activated carbon and lead-base inorganic pigment on the surface of the QCM. The identification of odorants is discussed in terms of comparison of their normalized patterns of resonant frequency shift and relative response intensities calculated from the response curve.
