A significant change in the electrical resistance of this sensor was observed with increasing 1-nonanal gas concentration; the resistance decreased by a factor of 1.12 within the range of 1 to 10 ppm at 300\u2009\u00b0C. The recovery of the sensor\u2019s resistance after detecting 1-nonanal gas concentrations of 0.055, 0.18, 1 and 9.5\u2009ppm was determined to be 86.1, 84.2, 80.4 and 69.2%, respectively.
