Web1 mrt. 2024 · According to Boyle’s Law, pressure and volume are inversely proportional. As the gas moves from the higher- pressure column head to the lower pressure outlet, it expands, increasing in volume. Thus, the volumetric flow rate calculated by equation 3 is the average volumetric flow rate and it is usually expressed in units of cm 3 /min or mL/min. WebINTRODUCTION. 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).
