摘要： In a liquid chromatographic system, a processor is configured to analyze a sample through a first stream which is an analysis flow path including a first column, to obtain at least one of a result of analysis for quality control of the first stream and information that specifies a sample to be analyzed in the first stream, to specify, among two or more combinations of a cleaning method and a cleaning execution condition, a first combination including an execution condition to which at least one of the result of analysis for quality control and the information corresponds, and to drive one or more cleaning pumps in accordance with the cleaning method included in the first combination.

摘要： A liquid chromatographic system includes a column, a needle, a valve, a pump, and an analysis flow path. The valve sets the analysis flow path by switching between a first flow path through which an eluent flows from the valve to the column via the needle and a second flow path through which the eluent flows from the valve to the column not via the needle. The first flow path can be cleaned by drive of a first cleaning pump while the first flow path is set, and the second flow path can be cleaned by drive of the first cleaning pump while the second flow path is set.

摘要： 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.
