Abstract of the Disclosure A novel and highly efficient flow injection analysis method is disclosed, in which in order to attain an extreme- ly high reaction rate of sample and reagent solutions at a reaction line, the solutions are injectedly supplied thereto alternately and respectively at a predetermined trace amount through independent two flow lines which are kept so as not to produce pulsation within the solutions. A thermostat bath accommodating the reaction line and a back pressure coil connected to the flow lines also make the aforemen- tioned reaction rate stable and regular. Spectrophotometric flow cell succeeding the flow lines for the analytical determination of the sample solution has a specific range of optical path length and such optical path diameter which is widely diverged from its inlet.
