| Outline of Final Research Achievements |
Temperature and humidity characteristics of a QCM coated with acrylonitrile styrene copolymer (AS) were studied as a CO2 sensor. Consequently, the following results were obtained. 1) A frequency shift of the QCM is in proportion to CO2 concentration under the condition of constant temperature. 2) The sensitivity for CO2 concentration decreases in a linear fashion with a rise in temperature. 3) The frequency shift increases in a parabolic fashion and the sensitivity for humidity increases in a linear fashion with a rise in humidity under the condition of constant temperature. 4) The sensitivity for absolute humidity decreases in a parabolic fashion with a rise in temperature under the condition of constant absolute humidity.
