Abstract
A chemical analyzer for measuring a concentration of components of a sample liquid, by mixing the sample liquid with reagents, so as to react the reagents upon the components thereof, includes a carrier having an introducing portion through which the sample liquid is injected, passages for distributing the sample liquid injected from the introducing portion, and plural reactor portions which hold the sample liquid therein to be mixed with the reagent, thereby to react. A movable driver portion is provided on which the carrier is mounted and a reagent charging device is provided for ejecting the reagents which are different for the respective plural reactor portions of the carrier, sequentially. Further, a detector is provided for detecting the components after mixing the reagents with the sample liquid.
