Eluent tank

The eluent tank (1) contains carbon dioxide under gasliquid equilibrium at 4.5 MPa and 10°C. It is a buffer volume in the carbon dioxide loop and its volume is about twice the volume of the column. A molecule of carbon dioxide will pass around the system about 15 times per hour. The external carbon dioxide storage tank needs to be only 50 times the volume of the column for one week of operation (compared with the required storage of solvent in HPLC which is 600-1000 times the volume of the column).
