Abstract
A liquid chromatograph includes a sample supplier that supplies a sample into a mobile phase, a chip column having a flow path that functions as a separation column on a substrate, a packed column, a switcher configured to be switchable between a first state in which a mobile phase and a sample are guided from the sample supplier to the chip column and a second state in which a mobile phase and a sample are guided from the sample supplier to the packed column, and a detector that detects a sample that has passed through the chip column and a sample that has passed through the packed column.
