Abstract

PURPOSE:To raise the accuracy of measurement, by making the body of a cell from a material of high absorbance. CONSTITUTION:The body 13 of a cell is made of black glass. Light-permeable glass members 15a, 15b are fuse-bonded on the side of the body 13 of the cell. Mask plates 14a, 14b made of black glass are fitted on the side of the body 13 so that a slit of length smaller than the circumference of the body 13 is defined by the mask plates. A part of light of a light source 7, which is obliquely introduced into the body 13 from the vicinity of the light-permeable glass plate 14b, light A1 produced near the cell and proceeding toward a tube 9a and other light A2 produced near the cell and directly entering into a constant-temperature vessel 2 are absorbed by the black glass of which the cell body 13 is made. Therefore, each light does not proceed toward a detector 8. This results in raising the accuracy of measurement.
