Conventionally, the proportion of oil contained in water has been measured by the intuition of an observer. That is, the observer estimated the oil content by smelling the smell of water. However, it was not possible to accurately measure the oil content due to individual differences in the sense of smell of the observer. Therefore, it was difficult to accurately detect water pollution in rivers, factory drainage channels, and the like.

て、油分の濃度を検出する。The odor sensors 10A, 10B and 10C are, for example, quartz vibration type odor sensors described in the specification of Japanese Patent Application No. 9-115589 filed by the present applicant. This odor sensor vaporizes the odorous substances contained in the water to be inspected (here, river water) with a vaporizer, removes the moisture in the vaporized gas with a cooling dehumidifier, and outputs the output of the cooling dehumidifier. Gas is introduced into the sensor cell. Inside the sensor cell, there is a crystal unit with an odor-sensitive film attached. When a volatile oil component or the like is adsorbed on the odor-sensitive film, the resonance frequency of the crystal unit shifts. By measuring this shift amount with a measuring circuit, the concentration of oil is detected.
