Sensoren fuer die selektive Bestimmung von Komponenten in fluessiger oder gasfoermiger Phase

The description refers to sensors in the form of field effect transistors and capacitors which are suitable for the qualitative and quantitative determination of analytes, e.g. molecules or ions in liquid or gaseous media. A special application area is the selective determination of the presence and concentration of gases. The sensors are characterized by the fact that they have a sensitive coating made of a heteropolysiloxane.
