摘要： A preparative chromatograph includes a separation column, and a detector provided downstream of the separation column. Furthermore, the preparative chromatograph includes a fractionator including a gas-liquid separator configured to separate a fluid containing components of a sample into a gas and a liquid, the fractionator being provided downstream of the detector. The preparative chromatograph is configured to supply carbon dioxide to a flow path between the separation column and the fractionator.

摘要： A first solution is supplied from a first pump. A second solution is supplied from a second pump. A flow path from the first pump and the second pump to a column is switched between a first flow path and a second flow path. In the first flow path, a first mixer is located upstream of an injection part for a sample, and the second mixer is located downstream of the injection part. In the second flow path, the first mixer and the second mixer are located upstream of the injection part. The first flow path is formed in a first mode in which the sample is diluted before introduction into the column. The second flow path is formed in a second mode in which the sample is not diluted before introduction into the column.
