This year the reviews of ion exchange and of liquid column chromatography are combined. It was logical to do this, for the techniques of high-performance liquid .chromatography include the use of ion exchangers. For one reviewer to report on two years' advances in liquid chromatography as well as in ion exchange is, however, a formidable task. It was made somewhat easier by the decision to include ion-exchanging thin-layer and paper chromatography in another review. "Liquid ion exchangers" are likewise omitted except for a few references to partition chromatography.To cite all the literature references in the two overlapping fields of ion exchange and liquid column chromatography is clearly impossible. Computer print-outs can be obtained from the abstract services, but a reviewer should do more than merely copy these lists. I preferred to peruse the Harold F. Walton joined the staff of the University of Colorado in 1947. His research interests in ion exchange date from 1938 when he went to work for the Permutit Co. as a research chemist; from there he went to Northwestern University in 1940. He obtained the BA and DPhil degrees at Oxford University. He is the author of three textbooks on inorganic and analytical chemistry and coauthor with William Rieman III of "Ion Exchange in Analytical Chemistry" published in 1970. He has contributed chapters on the physical and analytical chemistry of ion exchange to several cooperative works. In 1961 he was chairman of the Gordon Research Conference on Ion Exchange. Dr. Walton spent the 1966-67 academic year and half of 1970 as a Fulbright visiting professor at the University of Trujillo, Peru. He was a member of the Advisory Board of Analytical Chemistry.

“…Amino acid derivatives are more amenable to separation by non-ionic chromatography, and major emphasis has been given to the phenylthiohydantoin derivatives, which have been separated both by normal and reverse-phase methods (281-286). Separation of dansyl amino acids has also been reported (187).…”

“…For silica supports, coated with 3,3'-oxydipropionitrile (4), water (5), or formamid (5) and eluted with hexane or dichloromethane, pronounced influence from the support on the retention was observed for polar uncharged compounds and even at high loadings. The same observation was made with organic ammonium ions on silica columns coated with buffer and eluted with chloroform + 1-pentanol (3), but the support interaction was small at the maximal loading of the buffer.…”
