1. A preparative chromatograph comprising:
a separation column configured to separate components of a sample;
a detector provided downstream of the separation column, the detector being configured to detect the components of the sample separated by the separation column; and
a fractionator including a gas-liquid separator configured to separate a fluid containing the components of the sample into a gas and a liquid, the fractionator being provided downstream of the detector, the fractionator being configured to fractionate the components of the sample separated by the separation column based on a detection result of the detector;
wherein
the preparative chromatograph is configured to supply carbon dioxide to a flow path between the separation column and the fractionator.
