Abstract
PURPOSE:To permit an accurate optical analysis of liquid to be performed for a long time by forming an air layer between the surfaces of an optical analyzing apparatus and a sample liquid. CONSTITUTION:The bottom wall 4 of a container 1 filled with the sample liquid 2 is provided with a hollow thin pipe 5 so that is projects toward the light source 3 of the optical analyzing apparatus, the pipe 5 having an opening so small that if the liquid pressure of the sample liquid 2 is exerted, the surface tension does not allow the liquid 2 to enter. A container 7 having a light-receiving part 6 air- tightly constituted except for the junction with the pipe 5 is connected to the lower side of the pipe 5. This eliminates the need for a cell window between the sample liquid 2 and the light-receiving part 6 when the light from the light source 3 passes through the sample liquid 2 and reaches the light-receiving part 6 to make an optical analysis of the sample liquid 2. Eliminating the cell window which may be contaminated by the sample liquid 2 permits an accurate analysis to be continuously performed for a long time.
