Sample gas analyzing device and computer program for the same

摘要

A sample gas analyzing device (100) that quantitatively analyzes one or more measurement target components in a sample gas by performing a multivariate analysis using a spectral spectrum obtained by irradiating light to the sample gas, wherein the analyzing device is adapted to switch the library data between a first generation condition in a period of a predetermined time lapse after starting the sample gas generation and a second generation condition after the predetermined time lapse, wherein under the first generation condition, a plurality of measurement target components are quantitatively analyzed using the first library data obtained by compensating interference influence of measurement extra-target components; and under the second generation condition, the quantitative analysis of a plurality of measurement target components is performed using second library data obtained without compensating interference influence of the measurement extra-target components.
