Summary:Provided is a gas analyzer capable of measuring, by a simple configuration, the gas concentration of two components including nitrogen monoxide gas (NO gas) and nitrogen dioxide gas (NO2 gas), or three components also including sulfur dioxide gas (SO2 gas), included in a sample gas. A gas analyzer for calculating the gas concentration c1 of nitrogen monoxide gas (NO gas) from a calculated c0, cm, c3, and c2 on the basis of the gas concentration at the time of reaction consumption calculated by subtracting the measured gas concentration c3 of ozone gas (O3 gas) from the gas concentration c0 of supplied ozone gas (O3 gas) being equal to the gas concentration obtained by adding the gas concentration (c1 + c2 - cm)/2 of dinitrogen pentoxide gas (N2O5 gas) to the gas concentration c1 of nitrogen monoxide gas (NO gas) in a measurement subject gas.  L'invention concerne un analyseur de gaz capable de mesurer, par une configuration simple, la concentration en gaz de deux constituants comprenant du monoxyde d'azote gazeux (NO gazeux) et du dioxyde d'azote gazeux (NO2 gazeux), ou trois constituants comprenant également du dioxyde de soufre gazeux (SO2 gazeux), inclus dans un échantillon gazeux. Un analyseur de gaz est destiné à calculer la concentration en gaz c1 de monoxyde d'azote gazeux (NO gazeux) à partir de c0, cm, c3, et c2 calculées sur la base de la concentration en gaz au moment de la consommation de réaction calculée par soustraction de la concentration en gaz mesurée c3 d'ozone gazeux (O3 gazeux) à partir de la concentration en gaz c0 de l'ozone gazeux fourni (O3 gazeux) étant égale à la concentration en gaz obtenue en ajoutant la concentration en gaz (c1 + c2 - cm)/2 de pentoxyde d'azote gazeux (N2O5 gazeux) à la concentration en gaz c1 de monoxyde d'azote gazeux (NO gazeux) dans un gaz sujet de mesure.  簡易な構成でサンプルガスに含まれる一酸化窒素ガス(NOガス)および二酸化窒素ガス(NO2ガス)の2成分、または二酸化硫黄ガス(SO2ガス)を加えた3成分のガス濃度を計測可能とするガス分析計を提供する。 供給されるオゾンガス(O3ガス)のガス濃度c0から、測定されたオゾンガス(O3ガス)のガス濃度c3を、減じて算出された反応消費時のガス濃度が、測定対象ガス中の一酸化窒素ガス(NOガス)のガス濃度c1に五酸化二窒素ガス(N2O5ガス)のガス濃度(c1+c2-cm)/2を加えたガス濃度に等しいことに基づいて、算出されたc0、cm、c3、c2、から一酸化窒素ガス(NOガス)のガス濃度c1を算出するガス分析計とした。
