PURPOSE: To reduce the quantity of consumption of reagent and to increase the reliability of measurement by injecting a sample and the reagent in series into the flow of a carrier solution.
CONSTITUTION: A sample in a sample vessel 25 is sucked into a gauge tube 22 by a pump 19. Next, a valve 20 being switched, the pump is operated again to suck a reagent in a reagent vessel 26 into gauge tubes 24a and 24b. When a selector valve 18 is switched in this state, a carrier solution in a carrier tank 17 is made to flow via a pump 1, a pipeline 3 and a selector valve 20 and is led into the main channel in the state that the sample in the gauge tube 22 is held between the reagents in the gauge tubes 24a and 24b. Then, while passing through a reaction coil 9, the sample is made to react with the reagent, and measurement is conducted by a detector 10.
