The Rate of Movement of a Chromatographic Zone as a Function of Column Position, Initial Concentration and Initial Volume BY

ARTHUR

Two methods have been developed for the experimental study of chromatographic phenomena ; one is based on the variations in the concentration of the substance chromatographed in the filtrate from the column; the other depends on the movement of a zone on the column. The first method has been used by C:issidy,'>*ClaessonI3andWei1h~falherbe.~Jacobs and Tompkins5 have used both met hods, while the second procedure has been employed in investigations by Martin and Synge,6Austin
