摘要： On the bottom face of a measurement section, measurement electrodes and a reference electrode are formed and a solution supply pipe is opened. Then, if a predetermined electrolytic solution is supplied from the solution supply pipe, the electrolytic solution can be held on an electrolytic solution holding surface on the lower end of the measurement section, utilizing the with surface tension thereof for providing a gas reception portion. Since the electrolytic solution is exposed directly to the air, substances in a vapor phase (particularly, odor substances) are diffused into the electrolytic solution, causing an electric state to change. The substances in the vapor phase can be detected by detecting the electric state change. The electrolytic solution held on the lower face of the measurement section can be updated by further supplying more electrolytic solution.

摘要： A method for detecting and identifying a chemical substance in various phases such as a vapor phase and a liquid phase. The chemical substance being measured is diffused into a predetermined phase. Then, an electric state at an electrode existing in the predetermined phase is detected as a change with time based on the diffusion and absorption of the chemical substance on the electrode. A pattern of the change of the electric state with time is prepared. A fitting function based on the pattern is set and parameters of the chemical substance being measured are found. A distance between the parameters of the chemical substance being measured and parameters of the reference substance which is detected is determined. In the case of a detection of a chemical substance in a liquid phase, before detecting the electric state at the electrode existing in the liquid phase, a predetermined electrolytic solution is supplied around the electrode to stabilize the electric state of the electrode and then the liquid phase containing the chemical substance being measured is supplied to the electrode.
