1. A liquid chromatographic system comprising:
a first column that separates a sample for each component;
a first stream which is an analysis flow path including the first column;
one or more cleaning pumps that supply a cleaning solution to the first stream;
a memory in which two or more combinations of a cleaning method and a cleaning execution condition are stored; and
a processor, wherein
the processor is configured to
analyze a sample through the first stream and 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,
specify a first combination including an execution condition to which at least one of the result of analysis for quality control and the information corresponds, among the two or more combinations, and
drive the one or more cleaning pumps in accordance with the cleaning method included in the first combination.
