Abstract
A preparative liquid chromatograph includes a liquid chromatograph section, a trap section, an eluent supply section, a collector, and a flow path switching section. The flow path switching section is configured to be selectively switched to a component trap mode that connects the liquid chromatograph section and the trap section in such a way that a sample component separated in a separation column is trapped by a trap column of the trap section; and a collection mode that connects the eluent supply section and the trap section and connects the trap section and the collector in such a way that the components trapped in the trap column are eluted by an eluent from the eluent supply section and are guided to the collector.
