Abstract: | Two columns of 100 mm and 200 mm in diameter for bench-scale liquid chromatography were designed to obtain a small dead volume and an appropriately uniform distribution of liquid, and the values of the height equivalent to a theoretical plate were measured for three kinds of packing beads, Sepharose 4B, Cellulofine GC-700 m and Silica. A suitable pressure drop through a distribution plate and/or a packed bed helps to distribute liquid flow uniformly over the column diameter, and reasonable HETP values were obtained. |
