Abstract:
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 least at 3 calibration points for every component. An advanced mathematical procedure for batch wise calibration called ProCal2.0 is introduced to reduce the calibration effort nearly by a factor of three even for multi gas-analysis. By application of the procedure to sensitivity data sampled at binary Ethanol/H2 gas mixtures, it is demonstrated that, with this efficient calibration procedure, the analysis results are very close to those which are obtained when each sensor chip is individually calibrated.
