Abstract
Method for generating an automatic chemical analyzer for measuring given substances in samples in accordance with an enzyme-immunoassay including a turntable rotated intermittently at a given pitch and holding a number of reaction tubes arranged equidistantly along a periphery of the turntable 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, the 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; and a carrier discharge device for removing carriers out of reaction vessels. For respective samples, a reaction vessel is passed through the washing device by a plurality of times to perform a plurality of washing operations including the B-F separation.
