動サンプル注入装置。[Scope of Claim for Utility Model Registration] (1) In an automatic sample injection device for liquid chromatography, which aspirates a sample, injects it into a separation section, washes it with a washing liquid, and repeats this process thereafter, An automatic system characterized by aspirating the sample into the sample loop and simultaneously sucking the eluent in the sample loop into a microsyringe, pushing out the eluent from the microsyringe after sample injection, and cleaning the piping system including the sample suction needle. Sample injection device. (2) Using a six-way valve that communicates with the sample suction needle, one end of the sample loop, the other end of the sample loop, the separation section, the liquid supply section, and the microsyringe, aspirate the sample and direct the eluent into the microsyringe at one position of the six-way valve. 2. The automatic sample injection device according to claim (1), which performs cleaning by injecting a sample and extruding an eluent from a microsyringe at other positions of a six-way valve using suction. (3) The automatic sample injection device according to claim (1), which uses 200 μl or more of the eluent as a washing solution.
