A comprehensive performance test of LPO2-Ade38090/Glu30010 (thickness 100 µm), was conducted (Figure ). The response ΔR/R0 of that sensor to different concentrations of CO2 follows a linear trend (Figure ) indicating that no saturation is reached at the tested analyte concentrations. Even at 0.5% CO2 a reasonable response of ΔR/R0 = -1.8% is achieved. The response is stable upon cycling and is identical in air and N2 as carrier gases (Figure ). The response and recovery times during cycling is the same in both environments with tres = 25 s and trec = 60 s. Consequently, the presence of O2 does not influence the detection mechanism.
