A movable sample suction needle provided through a valve between the pump and the column and having a sample hole for sucking the sample in the sample bottle is placed in a seal chamber with a needle seal. is in place, the eluate flows from the pump via the valve through the liquid intake hole to the sample intake needle and the column, and the load pressure automatically closes the needle seal. In a liquid injection device that tightens around the outer periphery of the needle to increase airtightness, when the sample suction needle moves from the predetermined position in the seal chamber to aspirate the sample, the liquid in the seal chamber is compressed through the valve. A liquid sample injection device characterized in that load pressure is released. 2. In the liquid sample injection device according to claim 1 of the utility model registration claim, another eluent outlet is provided on the opposite side of the eluent inlet to the seal chamber, and a high pressure valve is provided in the flow path. A liquid sample injection device featuring: 3 Utility Model Registration Scope of Claims In the liquid sample injection device according to claim 1, the eluent sent from the pump is connected to a purge valve via a six-way valve and a seal chamber, and the other of the purge valves is connected to the inlet of a syringe. A liquid sample injection device featuring the following features. 4 Utility Model Registration Scope of Claim 1. The liquid sample injection device according to claim 1, characterized in that a flow path holding an additional resistance is connected to the discharge flow path of the syringe via a valve.
