御される試料前処理装置。[Scope of Claim for Utility Model Registration] A pretreatment device for a sample introduced into a liquid chromatograph, in which a first pump that sucks up a sample from a reaction vessel at a predetermined flow rate is connected to a sample circulation side and a sample collection side. A flow path is formed so that the sample from the sample circulation side outlet of the switching valve is returned to the reaction vessel, and the sample collection side outlet of the switching valve uniformly distributes the solution. It is connected to the inlet of a mixer that mixes and sends the sample to the sample introduction section of the liquid chromatograph, and the inlet of the mixer is further configured to dilute the sample collected by the switching valve to a predetermined dilution degree. A sample pretreatment device, which is connected to a second pump that sucks up the diluent at a flow rate, and is controlled so that the switching valve is switched to the sample collection side at a predetermined time and for a predetermined period of time.
