ABSTRACT:
A gas analyzer capable of simultaneously detecting two or more components in a single-cell mode and a gas-analyzing mechanism suitable for simultaneously detecting two or more components in a cross-flow modulation single-cell mode are provided. A gas analyzer unit includes two measuring cells, light sources provided on one end side of each of the measuring cells, gas filter cells with interferential gaseous components hindering a detection of components to be measured enclosed provided on the other end side of each of the measuring cells, beam splitters included in two gas filter cells, first- and fourth and second- and third detectors provided on the side of transmitting position and the side of reflecting position, respectively, of each of the beam splitters and a sampling device connected with a rotary valve.
