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