Packing quality assessment on the basis of the fluid-dynamic tests.

Test IDN (—)HETP/ (—) (—)

Before XAD2 (1.8 m, 3.1 m/h)1200.017271.3
After XAD2 (1.8 m, 3.1 m/h)570.037581.0
Before IRA1 (1.8 m, 2.8 m/h)460.045611.3
After IRA2 (1.8 m, 1.3 m/h)290.073991.8

The fluid-dynamic tests were performed at a 1.2 m/h superficial velocity. The velocities reported in the test ID refer to the PC breakthrough test performed before or after each fluid-dynamic test.
Number of theoretical plates in the column packing (—).
Height equivalent to a theoretical plate (m).
HETP/average size of the packing particles (—).
Asymmetry factor (—).
