Abstract
Apparatus in which a sample and a reagent solution are introduced into a stream of carrier liquid, whereby reaction proceeds between the sample and the reagent solution during their transfer through a passage. When a zone of the reaction solution passes successively through two flow cells provided in series, light absorbancy based on the reaction solution in each flow cell is measured, and rate assay is made from a difference between light absorbancies. A period of time for observing a specific sample can be changed by changing the length of a reaction tube connecting a flow cell at the upstream side to a flow cell at the downstream side.
