Introduction Most apphcatlons of the so-called quartz crystal sorption detector deal with the measurements of very small concentrations of atmosphenc pollutants f 1 - 51 In these apphcatlons the large theoretical sensltlvlty of sorption detectors 1s the most interesting parameter Problems anse here con- cerning the stability of the sensmg layer put on the quartz crystal surface and mterference with unwanted gases Furthermore, m some cases, when a thick sensing layer has to be apphed to the crystal to achieve a large sensltlv- lty, there can be some difficulty m keepmg the crystal osclllatmg For some practical apphcatlons, such as m process control or m the medical field (e g , U-I anaesthesla [6, 7, 8]), the requirements on the sorption detector are quite different In these apphcatlons the detector should have a fast, reversible and stable long-term response We have therefore performed some studies on quartz crystals covered with layers based on slhcone O&S, with these requirements m mind 0250-6874/82/0000-0000/$02 75 @ E lsevzer Sequoza/Prznted zn T he Netherlands
