Abstract
PURPOSE:To avoid displacement of each specimen in case of handling a large number of specimens by providing a pitch-detecting slit near a light-measuring slit in order to detect the position of specimens. CONSTITUTION:When a carrier A carrying a plurality of specimens is transferred onto a base table 7 of a photometric apparatus 1, a detection signal is outputted from a comparing circuit 4 side by the rise of the level of the signal outputted when one end portion of a specimen in one pitch passes a pitch detecting slit 3. Then, a detection signal is outputted from a comparing circuit 5 side by the fall of the level of the signal outputted when the other end edge of the same specimen passes the pitch detecting slit 3. Consequently, an AND circuit 6 is established. Then, the specimen feeder is ordered to stop the carrier A at a given position, and the fractional concentration of the specimen is measured by a light-measuring slit detection part 2.
