PURPOSE:To obtain serum information with respect to a specimen prior to performing the biochemical analysis of many items, by providing a serum pre- analytical apparatus to an automatic chemical analysis apparatus. CONSTITUTION:Sample containers 4 each storing a specimen are arranged to a sample cassette 5 and a light source part 8 and a light detecting part 9 are arranged in opposed relation to the cassette 5 so as to hold the same therebetween. The specimen in each sample container 4 is irradiated with light from the light source part 8 and light transmitted through the specimen is detected by the detecting part 9. Subsequently, the detection signal from the detecting part 9 is supplied to an operation circuit 12 through an amplifier 10 and a logarithmic converter 11. The operation circuit 12 receiving the detection signal calculates an absorbancy value of a specific wavelength on the basis of the output signal of the logarithmic converter 11 and the serum information in the specimen is calculated from the absorbancy value. Because the above mentioned serum pre-analytical apparatus is provided, serum information with respect to each specimen can be obtained prior to performing the biochemical analysis of many items. |
