HYDROGEN PEROXIDE GAS STERILIZING TREATMENT SYSTEM AND DETECTOR OF CONCENTRATION OF HYDROGEN PEROXIDE GAS IN THE SYSTEM AND DETECTION METHOD USING DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a detection method of the concentration of a hydrogen peroxide gas constituted so as to enable automatic measurement, a detector therefor and a hydrogen peroxide gas sterilizing treatment system which uses the detection method and the detector to enable the control operation suitable for the sterilization due to the hydrogen peroxide gas in an solator.;SOLUTION: The hydrogen peroxide gas sterilizing treatment system is equipped with the isolator 1 having gas sampling regions 2 at a plurality of places, a gas-liquid mixing tank 5 for receiving a sampling gas to mix and react the same with the potassium permanganese solution introduced by a chemical injection pump 7, a gas flowmeter 4 for measuring the flow rate of the hydrogen peroxide gas, a degassing tank 8 for defoaming the reaction solution in the gas-liquid mixing tank 5, an absorptiometer 9 for allowing the defoamed reaction solution to flow to measure absorbance and an operator 10 for operating the concentration of the hydrogen peroxide gas on the basis of the absorbance measuring result and the correlation of preliminarily calculated absorbance with the concentration of the hydrogen peroxide gas and constituted so as to detect the concentration of the hydrogen peroxide gas in a real time by measuring the absorbance of the reaction solution.;COPYRIGHT: (C)2006,JPO&NCIPI
