Notes:
An efficient system for preparative reversed-phase separations with packed glass columns is described. The advantage of this system is the use of relatively simple and inexpensive equipment.Column performance, load capacity, effect of the feed volume and the feed concentration on peak broadening are shown. The influence of the selectivity and the capacity factors on column load have been measured.The effect of the column dimensions is demonstrated by means of practical applications. The loading capacity of a column depends on the thermodynamic proporties of the separation system used. It is therefore not expedient in preparative chromatography to correlate the loading capacity of a column by means of grams dissolved per grams of adsorbent.
