Abstract

PURPOSE:To improve the reliability of a unit and also to reduce its cost by interposing a transparent body in a light passage in a sample cell and by changing the light- axial length of this transparent body in this light passage. CONSTITUTION:Sample cell 10 is arranged between light source 11 and photo detecting element 12. In sample cell 10, gaseous or liquid sample 13 flows and in the light passage of sample cell 10, rectangular transparent body 16 is interposed. Rotating this transparent body 16 in sample cell 10 varies the length of transparent body 16 in the light passage. After light source 11 is turned ON-OFF, transparent body 16 is rotated in sample cell 10 to obtain two states when the long side and short side of transparent body 16 are positioned in the light passage in sample cell 10. The measurement of the sample is carried out by making use of a difference between those two states.
