Abstract
A liquid chromatographic system includes a first cleaning pump that supplies a cleaning solution to a first valve, a selector valve connected to a first column and a second column, the selector valve switching an object to be connected to a detector that analyzes a separated sample between the first column and the second column, and a controller. The controller can have the first cleaning pump driven to clean the selector valve with the cleaning solution that flows through a first analysis flow path.
