Experimental investigation of the retention factor dependency of eddy dispersion in packed bed columns and relation to knox's empirical model parameters Vrije Universiteit Brussel KU Leuven
We report on a systematic and comprehensive (0.7 <= k ''' = 122) experimental study of the effect of the zone retention factor k'' on eddy dispersion (h eddy) in packed bed columns for liquid chromatography. The values for h(eddy) are obtained by subtracting rigorously estimated contributions to the total plate height from longitudinal diffusion (h(B)) and the mobile (h(Cm)) and stationary zone (h(Cs)) mass transfer resistances. For the first ...
