Abstract

La présente invention permet d'effectuer, via un processus unique, une erreur de pente et de point zéro de chaque ligne de tendance par rapport à une concentration de gaz émise par un capteur de mesure, ce qui permet d'éviter la nécessité d'un test de correction supplémentaire sur une valeur d'analyse de la concentration de gaz. Par conséquent, la fiabilité de la valeur d'analyse mesurée et analysée par le capteur de mesure est améliorée, et le processus d'analyse est simplifié.
