In chromatography, flow rates should be standardized for columns of different dimensions by expressing the flow rate as linear flow velocity (cm/h). This is defined as the volumetric flow rate (cm 3 /h) per unit cross-sectional area (cm 2) of a given column. However, flow rates are usually measured as volumetric flow rates (mL/min).
