A novel and highly efficient flow injection analysis method is disclosed, in which in order to attain an extremely 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 aforementioned 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. |
