Abstract
Automation of the collection and reinjection of a sample into a large number of containers is made possible without increasing the size of a liquid handler itself. A preparative liquid chromatography system includes a liquid delivery part () that feeds a mobile phase, a separation column (A;B) for separating a sample transported by the mobile phase, a plurality of liquid handlers (-to-n), each of which independently including a container arrangement portion () in which a plurality of containers for containing a sample are disposed, an injecting part (A) configured to suck a sample from a container disposed in the container arrangement portion () and hold it, and to inject the sample into the mobile phase fed by the liquid delivery part () by being interposed between the liquid delivery part () and the separation column (A), and a fractionation part () configured to collect a sample eluted from the separation column (A) so that the sample is fractionated to containers disposed in the container arrangement portion (), an injection switching part () configured to selectively interpose one of the injecting parts (A) of the plurality of liquid handlers (-to-n) between the liquid delivery part () and the separation column (A) by switching connection of channels at a position between the liquid delivery part () and the separation column (A), and a fractionation switching part () configured to selectively connect one of the fractionation parts () of the plurality of liquid handlers (-to-n) to a downstream side of the separation column (A) by switching connection of channels at a position downstream of the separation column (A).
