Abstract

See full text

An automatic chemical analyzer for measuring given substances in samples in accordance with an enzyme-immuno-assay includes a turntable rotated intermittently at a constant pitch and holding a number of reaction tubes arranged equidistantly along a periphery of the turnable to define a circular reaction line; a carrier supply device for supplying carriers into reaction vessels one by one at a given position in the reaction line, said carrier having given antibody or antigen fixed thereto; a sample delivery device for pouring given amounts of samples into reaction vessels at a given position in the reaction line; a washing device for washing reaction vessels and carriers contained therein to effect B-F separation; a color reagent delivery device for pouring given amounts of a color reagent into reaction vessels to form test liquids; a colorimeter for photometering the test liquids; a carrier discharge device for removing carriers out of reaction vessels; and a control device for controlling on and off operation of said washing device such that different reaction time periods for various test items can be set.
