To determine the presence of chemical compounds, we applied AC voltage to a titanium dioxide surface chemical sensor and recorded conductivity, surface potential and phase difference of the input voltage-output current wave form. This multidimensional information enabled us to distinguish alcohols and benzenes with a single detector. We also found that selecting the suitable type of surface electrode enhances sensitivity of the sensor.
