Chromatograph apparatus

A chromatograph apparatus, comprising:

• a preparative separation device in which a sample container holding a sample containing a target component and a preparative separation container for containing a target component obtained by preparative separation are to be arranged;
• a preparative-separation-and-analysis conditions setter configured to allow a user to set a preparative separation condition for the target component and an analysis condition for the target component after the preparative separation;
• a preparative separation executer configured to collect a sample from the sample container, separate the target component contained in the sample, and put the separated target component into the preparative separation container according to the preparative separation condition after the preparative separation condition and the analysis condition are set in the preparative-separation-and-analysis conditions setter;
• and
• an analysis executer configured to collect the target component from the preparative separation container and perform an analysis of the target component according to the analysis condition, after the preparative separation of the target component by the preparative separation executer.
