Abstract
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.
Claims9
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.
A preparative method using a preparative chromatograph, the preparative method comprising:
- separating components of a sample by a separation column;
- detecting the components of the sample separated by the separation column;
- fractionating the components of the sample separated by the separation column based on a detection result obtained by the detecting;
- separating a fluid containing the components of the sample fractionated in the fractionating into a gas and a liquid;
- and
- supplying carbon dioxide to the fluid containing the components of the sample before the fractionating of the components of the sample separated by the separation column.
