Patent ID: 6852282

Claim:
A chemical analyzer having a mechanism for mixing a reagent and a sample liquid to react a component within said sample liquid with the reagent, and enabling measurement of the component, comprising: an introduction portion for injecting said sample liquid therethrough; a positioning portion of a carrier, including: a branched flow passage for distributing said sample liquid injected from said introduction portion; a plurality of reactor portions for holding said sample liquid flowing down through said branched flow passage and for mixing with said reagent so as to enable reaction thereof; and reagent introduction portions, each being formed at a position corresponding to said reactor portions, and for introducing said reagent into said reactor portion; a reagent discharge means having a mechanism for discharging different kinds of reagents, one by one, for each of the reactor portions of said carrier; a position adjustment means having a mechanism for stopping said carrier to be positioned, temporarily, so as to adjust a relative position between said carrier and said reagent discharge means before introducing said reagent into said reactor portions; and a detector portion for detecting the component of said sample liquid after mixing said reagent and said sample liquid.
