Title:
A detecting method of a volatile organic compound
Document Type and Number:
Japanese Patent JP5955379
Kind Code:
B2
Abstract:
A method of using a sensor element includes: exposing a sensor element to an unknown analyte vapor; measuring a capacitance of the sensor element to obtain a measured capacitance; obtaining a true capacitance of the sensor element; exposing the semi-reflective conductive electrode to incident light and observing reflected light in order to measure a spectral change between the incident light and the reflected light; comparing the true capacitance and the measured spectral change, or at least one derivative thereof, to a reference library, the reference library comprising reference correlations between spectral change and true capacitance, or at least one derivative thereof, for a plurality of reference analyte vapors; and determining at least one of the chemical class or identity of the analyte vapor.
