Fig. 3. Visualization of MIMM readout data and temperature stability.
a Acquired MIMM readout data for the four analytes at various concentrations. The data are acquired at concentration steps of [10%, 25%, 50%, 75%, 100%] for CO2 and CH4, [100, 500, 1000] ppm for NH3, and [200, 400] ppm for MEK. The height of the color bars indicates the concentration in the steady state, and the scale is displayed on the right y-axis. The width of the color bars represents the duration of the data acquisition at the specific concentration. Note that for better visibility, the twenty-channel readout values are offset by steps of 0.05, 0.1, 0.005 and 0.005 per channel in the plots for CO2, CH4, NH3 and MEK, respectively. b Recorded MIMM temperatures during data collection. The measured temperatures are almost entirely in the range of 28 ± 0.05 °C
