P5.3 - Efficient Calibration and Recalibration of Metal Oxide Gas Sensors by a New Mathematical Procedure

Rolf Seifert, Hubert B. Keller, Kevin Frank & Heinz Kohler
There is a growing need of economic online and in-situ field analysis applications like discriminated monitoring of toxic gas leakages, online monitoring of volatile components in chemical and biochemical processes, quality monitoring in food processing, etc. In this context, the isothermally operated metal oxide gas sensors (MOGs) with tin oxide as base material are manifold introduced due to their high sensitivity, long-term stability and low price. Their sensitivity to specific gas components, however, cannot be...
