Abstract
A liquid chromatography (LC) that can supply a mobile phase to a storage bottle and can prevent mixing of air bubbles into a flow path without stopping analysis and liquid feeding. The LC includes a liquid feeding device that feeds out a mobile phase, a sample injection portion that injects a sample into the mobile phase, a column that separates the sample carried by the mobile, and a detection device that detects the sample. The LC further comprises a storage bottle that stores the mobile phase fed by the liquid feeding device, a mobile phase supply bottle that supplies the mobile phase to the storage bottle, a mobile phase supply pump that supplies the mobile phase to the storage bottle, and a control unit that controls an operation of the mobile phase supply pump and determines an amount of the mobile phase to be supplied to the storage bottle.
