Separation of amino acids on ion exchange paper

Abstract

It is very useful to employ ion‐exchanging chromatography papers for a rapid separation of a mixture of amino acids. Various separations are described, in some cases taking only one hour. Special papers were developed for this purpose based on chemical modification of cellulose and containing basic or acid groups. The possibilities for using these papers in a quantitative determination are discussed.

A Quantitative Chromatographic Determination of Cysteic Acid in Amino Acid Mixtures on Ion Exchange Papers.

“…These papers, made by chemical modification, will be produced by Macherey and Nagel in Dtiren, Germany, and will be available with strongly or weakly acid or base groups. They have proved to be very useful in separating mixtures of compounds with ionic groups, especially amino acids (5).…”
