Webthe bed height, where taller beds are less sensitive to the contribution of the distribution system. It was also obvious that the larger the column, the larger was the contribution from the distribution system (Fig 3). In the 50mm column the results only look questionable for 5 µm particles below a 10 cm bed height. Webbetween the pressure drop over a packed bed of DEAE Sephadex A-25 and the flow velocity in a 5 cm i.d. column with a bed heightof approximately 10 cm. The curve is essentially linear in the typical operating range up to 0.15 bar where the flow velocity is about 380 cm/h. The maximum pressure drop (i.e., the pressure drop where

Webwhere. a = First half peak width at 10% of peak height b = Second half peak width at 10% of peak height. A s should be as close as possible to 1.0. A reasonable A s value for a short column as used in AC is 0.80 to 1.80.. An extensive leading edge is usually a sign that the medium is packed too tightly and extensive tailing is usually a sign that the medium is … Webheight or at ½ peak height. Retention and peak width are used to calculate various performance measurements; in this way, the separating power of a system can be calculated and compared. However, in order to do this, the chromatographer must rely on two fundamental theories of chromatography: (i) the plate theory; and (ii) the rate theory.
