<p>PURPOSE:To simplify the constitution of the titled analyser, by detecting one of bidirectionally emitted lights by a detection part having sensitivity to the absorbing band of a measuring component through a measuring cell while detecting said light and the reflected light from the measuring cell to control the quantity of incident light to one of both detection parts. CONSTITUTION:One of lights from a bidirectional light emitting source 11 is passed through a measuring cell 12 to be received by a first detection part 15 through a filter 14 while the light in the opposite side of the cell 12 and the light by the reflective mirror 13 in the cell 12 are received by a second detection part 17 through a filter 16 and the signals from the detection parts 15, 17 are inputted to a signal processing part 19. The detection parts 15, 17 are respectively set so as to have sensitivities to the absorbing band of a measuring component and that of an interference component and the quantity of incident light to the detection part 17 can be adjusted by an adjusting part 18. By this method, the interference component can be compensated by the single measuring cell 12.</p> |
