Abstract
To determine a corrected flow rate value of a mobile phase flowing in a liquid chromatography (LC) system, a flow rate of the mobile phase at a selected reference position in the LC system is measured to produce one or more flow rate values. A model of the LC system is applied to the flow rate value(s) to determine the corrected flow rate value(s). The model includes a distribution of capacitive elements and resistive elements arranged according to a topology of the LC system. The capacitive and resistive elements are representative of system and solvent properties affecting flow rate while operating the LC system. The system and solvent properties may be properties affecting the flow rate while operating the LC system under dynamic conditions.
