Abstract
A liquid sending pump supplies an eluent. A first sample supplier supplies a sample to a first separation column used for an analysis of the sample. A second sample supplier supplies a sample to a second separation column used for separation of the sample. A detector detects a sample that has passed through the first separation column or the second separation column. A flow-path switching valve is switchable between a first flow-path state in which an eluent that has been supplied by the liquid sending pump to the first separation column and a sample that has passed through the first separation column to the detector and a second flow-path state in which an eluent that has been supplied by the liquid sending pump and part of a sample that has passed through the second separation column to the detector.
