This paper presents a sheath flow multiple sample injector that realizes concentration-conservative sample injection. Stepwise flow is used to reduce the dilution of the sample reagent. Based on the CFD simulation results, it is estimated that sample reagent is diluted to 94% in a conventional sample injector. With stepwise flow, however, the level of dilution is reduced and the average concentration is estimated to be near 100%. For the experiment evaluation, a sample injector is fabricated and the sample injection using stepwise flow is visualized using a fluorescent measuring system. The accuracy of the injected sample volume and the feasibility of multiple sample injection are evaluated based on the experiment results.
