“…In recent years there has been extensive investigation of the operation of these devices in liquids. TSM sensors for use in gas and liquid phases have been extensively reviewed [1, [5][6][7][8][9][10][11][12]. Recent advances in TSM device design include a 30 MHz device using a specially thinned plate [29].…”

“…Sensing materials were reviewed in the previous chapter in this series [1] and in other publications [6,7,9,13,15,17,18]. Polymers are useful for organic vapor sensing because they offer rapid reversible vapor sorption, their selectivities and other properties can be altered by chemical structure, and they can be applied as thin films by a variety of techniques.…”

“…A variety of selective materials have been investigated for the detection of various analytes (21,(24)(25)(26)(27)(28)(29). Because reversible absorption is not 100% selective, the use of sensor arrays with pattern recognition has been investigated as a means of improving selectivity in the identification of toxic vapors and in multicomponent analysis (9,(30)(31)(32)(33)(34).…”

coustic wave microsensors are a satile class of sensor with y applications. Although origially regarded as mass detectors, hese sensors can also measure a ion via mass sensitivity. focus on sensing i or behavior in the liquid ph e will begin Part II with a di , -Acoustic devices are usually converted to chemical sensors by the application of a chemically selective layer (1). Polymer materials have been used in organic vapor sensing applications because vapor sorption in rubbery polymers is rapid and reversible; polymers form adherent thin films; and selectivity can be tailored by varying the chemical structure. Before discussing vapor sensors in the next section, we will consider the inherent sensitivities of acoustic Department Richard M.

“…Film-coated quartz crystal microbalance sensors have enabled the detection of various individual pollutants [2][3][4], and are used for the online detection of organic compounds [5]. The response properties of the sensor are affected by physical structure and chemical character of the sensing film.…”
