摘要

PROBLEM TO BE SOLVED: To provide a method and device for performing measurements at normal temperatures when measuring total organic carbon substances included in analysis gas.;SOLUTION: According to this gas analysis method, in an oxygen atmosphere, gas including organic carbon is low-temperature plasma-treated in a system where a metal-carrying catalyst exists, thereby measuring the total organic carbon amount in the gas. This device for gas analysis includes a means for supplying the gas including organic carbon to a reactor; a means for supplying oxygen to the reactor; a low-temperature plasma reactor filled with the metal-carrying catalyst; a high voltage power supply for impressing a voltage on the reactor; a measuring instrument for CO₂; and a means for discharging gas produced by decomposition/treatment at the plasma reactor. Since low-temperature plasma and the catalyst are jointly used to oxidize organic carbon at normal temperatures/normal pressures according to these method and device, these method and device are simple, neither requiring a heat-resistant structure for the device nor requiring preheat for a catalyst layer.;COPYRIGHT: (C)2005,JPO&NCIPI
