範囲第１項に記載の溶媒混合装置。[Claims for Utility Model Registration] Analyzing a solvent using 12 or more solvent reservoirs, a helium gas supply channel for supplying helium gas to these solvent reservoirs, and a liquid delivery pump from each solvent reservoir. In an apparatus that is equipped with a mixed liquid feeding channel for feeding a mixture of liquids to a system, and is configured to replace dissolved air in each solvent with helium gas, and then feed a mixture of each solvent. A solvent mixing device characterized in that the flow path is provided with an outside air introduction flow path through which outside air can be introduced when the pressure in the helium gas supply flow path is negative. 2. The 'solvent mixing device' according to item 1 of the 'Utility Model Registration Claim', in which the outside air introduction flow path is constructed by interposing a filter in the communication part that communicates from the outside air to the helium gas supply flow path. 3. The outside air introduction flow path The solvent mixing device according to claim 1, which is a utility model registration, and is constructed by interposing a check valve in the communication portion leading from the outside air to the helium gas supply channel.4. The solvent mixing device according to claim 1, which is a utility model, and is configured by interposing a flow path resistance consisting of a capillary tube and a filter in a communication portion communicating with the gas supply flow path.
