PURPOSE: To achieve higher efficiency in the detection and qualitative and quantitative operation of various chemical material, by analyzing chemical material applying a recognition mechanism of a living body and utilizing electric oscillation to enhance the selectivity of organic material.
CONSTITUTION: An electrostatic capacitance component (C) of an oscillation circuit is made up of a liquid 1 to be inspected and two electrodes 2 immersed facing it. When the liquid 1 is adsorbed on the electrodes 2, the amplitude of a oscillation signal is reduced. This enables the estimation of a high polymer compound and surface-active substance on the electrodes 2, which enables quantitative measurement such an antigen-antibody reaction and agglutination reaction of lectin and the like. In addition, the determination of various inorganic ions, lipid, protein and the like in a solution is made possible by using information on the capacitance (C). Non-sine wave used for the oscillation wave offers identifying information of chemical species by analysis of the waveform thereof. The oscillation pattern contains chemical information.
