Zusammenfassung:	The present disclosure relates to an apparatus for regulating the average mobile phase density or pressure in a carbon dioxide based separation system. The apparatus includes a controller, a set of pressure or density sensors and a set of instructions capable of determining the pressure drop across a column and adjusting at least one system component or parameter to achieve a pre-determined average mobile phase density or pressure in the system.
