The clear separation that was obtained between the acids was confirmed by the negligible cross contamination found between the acid peaks. Furthermore, the Sephadex LH-20 column gave a convenient elution volume and time similar to those found for a Celite Analytical Filter Aid column, without the progressive deterioration in separation normally associated with Celite.en© 1977 ARC – Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
