Dec 21, 2001 · The void volume of the column, Vo, was found by taking the product of the time of the peak absorption reading and the flow rate, which equaled 14.19 mL. This void volume was used as a basis of determining the V/ Vo value for ovalbumin. Table 1: Ovalbumin Elution Results

Void Volume ( Vo ): Also called interstitial volume or exclusion volume; It is the volume of solvent (mobile phase) that is located between the column packing particles. Pore Volume ( Vi ): Pore volume of all particles. Mobile Phase Volume (Vt ): Vt = Vo + Vi. Gel Volume ( Vg ): Volume occupied by the solid support (gel).

The void volume for each column was calculated by taking the time at which the peak of the Blue Dextran curve occurred, converting it to minutes, and then multiplying by the flow rate. The void fraction could then be obtained from dividing the void volume by the total volume of the column (which was calculated by geometric measurements).

The total volume of air attributed to each class of voids is calculated by multiplying column 7 by column 8, which contains the volume of one void of the class diameter, to give the air content as a fraction and then multiplying by 100% to express this as a percentage. The result is placed in column 9.

Which is equivalent to a volume flow rate of 16,88 m3/s when using a molar density of 1,09 kgmol/m3. A maximum allowable flow rate in the reactor lead to a cross section area of 6,75 m2 ,when assuming a catalyst void fraction of 0,5. This will lead to a total number of 5373 tubes inside the reactor shell.
