Preparative chromatograph system

Abstract

A preparative chromatograph system includes a sample injector (10) that injects a sample into a separation flow path (8) through which a mobile phase flows, a separation column (12) that is provided on the separation flow path (8) and is to separate a sample injected into the separation flow path (8) into components, a detector (14) that is provided at a position farther downstream than the separation column (12) on the separation flow path (8) and is to detect sample components obtained by separation in the separation column (12), a collector (18, 18′) having a plurality of collection containers (22) for collecting part of an eluate eluted from the separation column (12) and a switch mechanism (20, 30, 32) configured to be capable of selectively connecting a downstream end of the separation flow path (8) to any one of the collection containers (22), a collection setter (26) configured to set a portion, to be collected in each of the collection containers (22), of an eluate eluted from the separation column (12) using a pre-acquired chromatogram of a sample, and a collection setter (26) configured to be capable of setting a portion, including a sample component, of an eluate eluted from the separation column (12), and a portion, between two sample components that are adjacent to each other on the chromatogram, of an eluate eluted from the separation column (12), as the portion to be collected, and a controller (28) configured to control an operation of the switch mechanism (20, 30, 32) of the collector (18, 18′) and collect the portion, which is to be collected and is set by the connection setter (26), in the predetermined collection container (22).
