Abstract

PURPOSE:To enable to perform an acurate analysis, by a method wherein, in case a sample, such as blood, urine, and a reagent react to each other and a colorimeteric analysis is conducted, and in each of two terms in which they part from each other during a given period of time after an extinction degree is saturated, an extinction degree measurement is continuously carried out a plurality of points of time of find a mean value. CONSTITUTION:After a light from a light source 1 transmits through a liquid to be measured in a reaction tube 2 in which a sample and a reagent are mixed, it is detected by a photoelectric tube 3. The output of the photoelectric tube 3 is amplified, and is transferred to first and second counters 5A and 5B. The operation time of the two counters 5A and 5B is controlled by a controller 6. Or, the counter 5A counts at a plurality of points of time during a given period of time lapsing from the time when an extinction degree saturates the output of the amplifier 4, and the counter 58 counts at a plurality of the output of the amplifier 4, and the counter 58 counts at a plurality of points of time during a given period of time lapsing from the time when counting of the counter 5A is complete. An arithmetic unit 7 computes a means value of results at a plurality of points of time when each of the counters 5A and 5B counts, and compares whether a difference in a mean value is within a reference value. If the difference is within the reference value, it is outputted as an extinction degree at reaction final terminal to a printer 8.
