J. Auge et al., VERSATILE MICROCONTROLLED GAS SENSOR ARRAY SYSTEM USING THE QUARTZ MICROBALANCE PRINCIPLE AND PATTERN-RECOGNITION METHODS, Sensors and actuators. B, Chemical, 26(1-3), 1995, pp. 181-186
A new gas sensor array system for the detection of special gases or so
lvent vapours using the microbalance principle is presented. Different
coatings (e.g. polymers, cage structures, self-assembled monolayers)
as sensitive materials on the quartz surface allow the sensor array co
nfiguration. This gas analyzer system and the knowledge of effective c
hemical sensitive coatings open a great variety of special application
cases, e.g. in the environmental and chemical industry or biotechnolo
gy. After a short discussion of the theoretical background, experiment
al results with calixarene coated quartzes and the first results with
a gas chromatographic column are shown. Finally a brief description of
investigations with pattern recognition methods using the principal c
omponent analysis and neural networks is given.
