Abstract

Methodologies, systems, and computer-readable media are provided for controlling the mass flow rate within a CObased chromatography system. The pressure within a COpump is measured and received at a computing system, and the computing system retrieves a target temperature value corresponding to the new pressure measurement within the COpump. The computing system then generates a temperature control command that controls a COpump heater or cooler in order to achieve the target temperature value at the COpump. Thus, a target mass flow rate of COfrom the COpump is achieved by adjusting the temperature of the COpump in response to changes in pressure.
