LIQUID CHROMATOGRAPHY DEVICE AND LIQUID CHROMATOGRAPHY

摘要

A liquid chromatography apparatus A is provided with a sample preparation unit 1, a column 52 that separates components of a sample, an eluent supplier that includes a feeder 3 for supplying eluents La and Lb to the column 52, a flow path directional valve 2 capable of introducing fixed amounts of the sample and the eluents La and Lb to the column 52, an analyzer for analyzing a test solution composed of the sample components separated by the column 52 and the eluent La, and a controller 6, wherein the eluent supplier supplies the eluents La and Lb to the flow path directional valve 2 in an unmixed state. As a result of employing this configuration, analysis time is shortened and eluent consumption is reduced.
