発明の名称 (英語) ION CONCENTRATION MEASURING DEVICE AND ION CONCENTRATION MEASURING METHOD 新技術説明会
発明の概要(英語) An ion concentration measuring device 1 suppresses the effects of noise, and measures directly the concentration of ions contained in an object being measured. More specifically, the ion concentration measuring device 1 obtains the concentration of potassium ions 102 present in an object being measured 100. The ion concentration measuring device 1 is provided with: a first electrode portion 2; a sensor portion 3 which generates a current corresponding to a voltage provided to a voltage generating portion 6 and to the object being measured 100; and a control portion 8 which obtains the concentration of the potassium ions 102 on the basis of the current output from the sensor portion 3. The control portion 8 includes: a current value acquiring portion 17 which obtains a first current value (C1) generated by the sensor portion 3 when a positive voltage is provided, and which obtains a second current value (C2) generated by the sensor portion 3 when a negative voltage is provided; a difference acquiring portion 18 which obtains a difference (∆C) between the first current value (C1) and the second current value (C2); and a concentration acquiring portion 19 which obtains an ion concentration (T) on the basis of the difference (ΔC).
従来技術、競合技術の概要(英語) BACKGROUND ART
In the field of agriculture, including a large amount of a particular component has been attracting attention as a so-called functional vegetables. Results in recent studies, vegetable and the components contained therein and the specific ion in the soil indicates that the relationship. As a technique for measuring the concentration of a particular ion, for example, such as a flame photometer or liquid chromatography of light is known.
Furthermore, measurement of the concentration of ions in the field of technique, simplify the measurement operation has been desired. Is in such a technique, the sample was collected from the soil or medium, the specimens using a technique of measuring ion concentrations. For example, a portable instrument is the potassium ions, the water in the soil and collected using a syringe, the water was utilized to measure the ion concentration. In addition, the oxidation-reduction reaction in the measurement device has also been known.
