Abstract
When a flow path switch valve is in a first flow path state, an aqueous solvent supplied by an aqueous solvent supplier is guided to a first flow path, and a pH of the aqueous solvent is measured by a pH meter provided in the first flow path. When the flow path switch valve is in a second flow path state, the aqueous solvent supplied by the aqueous solvent supplier is guided to a second flow path. A sample to be analyzed is supplied by a sample supplier at a position farther downstream than the flow path switch valve. The solvent that has passed through the second flow path and the sample supplied by the sample supplier are guided to a separation column. The sample that has passed through the separation column is detected by a detector.
