PURPOSE:To enable automation of a nephelometry or a turbidimetry utilizing an antibody antigen reaction by making the calibration curve with which the concn. of the antigen or antibody, scattering intensity and absorbancy attain a linear relation only with the calibrator for a concn. rate and the known concn. at an optional one point. CONSTITUTION:A sample vessel 44 is supplied to a sampling position and a specified amt. of serum is held in a probe 41 by a pipetter 40, is transferred to a discharge position 45 and is discharged into a reaction vessel 22. The vessel 22 passes through a luminous flux 26 during rotation of a disc 21. The output from spectroscope 27 is taken into a central processing unit 50 via an A/D converter 54. The unit 50 detects the concn. of an antigen or antibody by utilizing the calibration curve which is formed only from the calibrator of a concn. rate and the known concn. at optional one point and at which the concn. of the antigen or antibody, scattering intensity and absorbancy attain a linear relation. |
