Title:
GAS MEASUREMENT DEVICE, AND METHOD FOR DETERMINING CONCENTRATION OF COMPONENT OF INTEREST
Document Type and Number:
WIPO Patent Application WO/2024/034488
Kind Code:
A1
Abstract:
The concentration of each of a plurality of gas components is expressed as a corrected concentration obtained by subtracting, from a pre-correction concentration corresponding to a detected value for said gas component, a measurement error to which the measurement of said gas component is subject due to one or more interfering components affecting said gas component. The measurement error to which the measurement of the gas component is subject is expressed by a linear sum of corrected concentrations of the interfering components affecting said gas component and influence coefficients indicating the degree to which said interfering components influence the measurement of said gas component. According to the relationship between the corrected concentration and the pre-correction concentration for each of the plurality of gas components, the concentration of a component of interest is determined on the basis of the multiple influence coefficients and the respective detected values for said plurality of gas components.
