PURPOSE: To measure both biochemical and immunochemical items without adding a specific measuring device by forming a sample room with a hole passing only the light flux transmitting through a sample solution on the front of an incident slit of a spectroscope.
CONSTITUTION: The longitudinal incident slit is formed on a wall dividing between the sample room 22 and the spectroscope 26 and an annular scattered light detector 23 having a longitudinal hole is attached to the periphery of the incident slit on the sample room 22 side. Outputs from an optical detector 25 and the scattered light detector 23 are amplified by an amplifier 27, inputted to a multiplexer 28 and then converted into a digital signal by an A/D converter 29. The digital signal is processed by a central processing unit CPU 30 and displayed by a proper means. In said constitution, biochemical multi-item analysis using both colorimetric and rate methods and immunochemical item analysis using light scattering method are effectively performed and both the biochemical and immunochemical items can be measured without adding the specific measuring device.
