Optimization of Working Conditions for Perovskite-Based Gas Sensor Devices by Multiregression Analysis

Figure 10

Fractional sensitivity time profile against 100, 150, and 200 ppm of carbon monoxide, that are represented with a black, gray, and white circle, respectively, when gas sensor device is under different operating conditions: temperature spans the values from 300 to 380 and 460°C; inlet-gas flow rate spans the values from 40 to 70 and 100 cm³/min.
