초록 | The axial packing uniformity of preparative-scale liquid chromatography columns was studied by measuring overall column properties for different column lengths. Theproperties investigated were packing density, external porosity, permeability, and columnefficiency. Two different chromatographic materials were compared. The columns madewith small and spherical particles were more homogeneous and had lower dependence ofcolumn properties on column length than the columns with large, irregular-shapedparticles. Column efficiency of short columns was lower than that of longer columns,because of column entrance effect and wall effect. |
