SENSOR AND A DEVICE FOR MEASURING THE CONCENTRATION OF NITROSOTHIOL, CAPABLE OF MEASURING SIGNALS FROM TWO SUBSTANCES WITH ONE ELECTRODE BY DISTINGUISHING THE SIGNALS

摘要

PURPOSE: A sensor and a device for measuring the concentration of nitrosothiol are provided to enable to measure signals from nitrosothiol and nitrogen oxide by distinguishing the signals with a single electrode so that concentration measurement of the nitrosothiol with reliability is possible by excluding a disturbing effect of the nitrogen oxide.;CONSTITUTION: A sensor for measuring the concentration of nitrosothiol comprises an electrode(11) and a RSNO(nitrosothiol) photolysis initiating and terminating unit. The electrode measures current generated by an oxidation reaction of NO(nitrogen oxide). The sensor measure the current generated by the oxidation reaction of NO before and after the photolysis of the RSNO. The RSNO photolysis initiating and terminating unit introduces the electrode to an optical fiber. The RSNO photolysis initiating and terminating unit is an optical catalyst switch controlling a supply and cut-off of lights from a light source to the optical fiber after mounting the light source to the optical fiber in which the electrode is introduced.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Light source off; (BB) Light source on
