Abstract
An organic solvent containing liquid that does not include a component to be detected by a detector is used as a first solvent, and an organic solvent containing liquid that includes the component to be detected and is adjusted to have a concentration of an organic solvent that prevents a separation column from actually holding the component to be detected is used a second solvent. Further, a mobile phase is sent while a setting value of a concentration of the second solvent in the mobile phase is changed over time with the separation column provided on an analysis flow path, and an actual concentration of the second solvent in the mobile phase is found based on a detection signal of the detector when the mobile phase is sent at each setting value.
