LIQUID MIXING APPARATUS, AND LIQUID CHROMATOGRAPH

摘要

PROBLEM TO BE SOLVED: To provide a liquid mixing apparatus configured to reduce and stabilize the density unevenness in a flow direction, and to provide a liquid chromatograph using the liquid mixing apparatus.SOLUTION: A liquid mixing apparatus includes: a first introduction passage with a first eluant passing therethrough; a second introduction passage with a second eluant passing therethrough; a first branching point disposed in the first introduction passage and branching off the first eluant; a second branching point disposed in the second introduction passage and branching off the second eluant; first and second merging points in each of which the first eluant branched off from the first branching point merges with the second eluant branched off from the second branching point; a first merging passage where a liquid mixture of the first and second eluant merging at the first merging point passes therethrough; a second merging passage where the liquid mixture of the first and second eluant merged at the second merging point passes therethrough; and a third merging point where the first merging passage merges with the second merging passage. A passage time of the liquid mixture in the first merging passage is different from that of the liquid mixture in the second merging passage.
