P1.9.10 Batch-wise Calibration of Multi-Gas-Sensors and Calibration Models for Mono Gas and Multi Gas Applications

Hubert B. Keller & Rolf Seifert
Although sensor chips for multi-gas-sensors are usually batch-wise fabricated, each sensor chip has to be individually calibrated to yield a high analytic performance. For multi gas applications, a sensor chip normally has to be measured for calibration at about 5 calibration points for every component, A new mathematical procedure for batch-wise calibration called ProCal was developed and extended to reduce the calibration effort nearly by a factor of five even for multi-gas-analysis. By application of...
