Chemical identification using an impedance sensor basedon dispersive charge transport

Impedance spectroscopy has been used to identify analytes in semiconducting metallophthalocyanine thin films. Above a critical concentration, the magnitudes of the high frequency conductivity changes are invariant with concentration but distinct for different analytes and can be used for analyte ide...

description Impedance spectroscopy has been used to identify analytes in semiconducting metallophthalocyanine thin films. Above a critical concentration, the magnitudes of the high frequency conductivity changes are invariant with concentration but distinct for different analytes and can be used for analyte identification. The analyte-induced ac conductivity changes above 5 kHz have been converted to frequency shifts in a circuit resonance and used to differentiate methanol, ethanol, and isopropanol vapors in a nitrogen carrier gas. The analyte-induced changes in the conductivity are consistent with analyte-induced changes in the charge relaxation times.
