Preparation of low concentration H2 test gas mixtures in ambient air for calibration of H2 sensors

“…A major challenge for electrochemical measurements of trace gas components in ambient air are potential errors caused by interference, drift and aging of gas sensor electrodes (Pang et al, 2017;Roberts et al, 2017;Roberts et al, 2012;Jasinski et al, 2018;Aiuppa et al, 2011). Frequent calibration and thorough characterization of the sensors used are key to measure correct concentrations and thus to generate high-quality data (Kamionka et al, 2006;Hasenfratz et al, 2012;Tian et al, 2019;Korotcenkov et al, 2009).…”

“…Frequent calibration and thorough characterization of the sensors used are key to measure correct concentrations and thus to generate high-quality data (Kamionka et al, 2006;Hasenfratz et al, 2012;Tian et al, 2019;Korotcenkov et al, 2009). The environmental conditions at the measurement site can significantly change the response and sensitivity of the sensors (matrix effects) (Baron and Saffell, 2017;Pang et al, 2017;Lewis et al, 2016;Jasinski et al, 2018;Tian et al, 2019;Korotcenkov et al, 2009;Farquhar et al, 2021). The quality of measurements carried out with electrochemical sensors can therefore be significantly improved if the sensors are calibrated under ambient conditions directly before the measurement.…”
