PURPOSE:To utilize effectively a waiting time necessary for a color developing reaction of each measuring cell for a measuring preparation of another measuring cell by using the plural measuring cells of an absorptiometer and transferring and transferring said cells automatically to set in an optical path of the photometer. CONSTITUTION:An optical path of the absorptiometer consists of a light source block 1, the measuring cell 2, an interference filter 3 and a photodetected signal detecting part 4. Measuring cells 2 are mounted on a long and narrow measuring cell base 5 at equal spaces in order, the base 5 is moved for front and rear directions by a driving motor 6 and the position is set exactly by a light transmitting hole 8 and a photosensor 9 of a revolving plate 7. For measuring the absorbances of the samples in many cells 2, the first measuring cell is set in the measuring optical path, the absorbance is measured, then the second said cell is set in the optical path. In such a way, the cells are set in order and the absorbances are measured. |
