摘要:
A liquid chromatograph includes pumps for supplying solvents, a mixer for mixing the solvents, a controller for controlling a mixing ratio of the solvents in the mixer, a chromatograph column for separating a sample carried with the solvents, a flow path control valve for supplying the sample together with the solvents to the chromatograph column, and a detector for detecting the sample supplied thereto, wherein the mixer includes a mixing chamber and a porous medium accommodated in the mixing chamber, the porous medium having a size and shape in conformity with a size and shape of said mixing chamber such that no substantial gap is formed between an outer surface of the porous medium and an inner surface of the mixing chamber.
