Technique for the Separation of Ink Dyestuffs with Similar Values

CODEN: JFSCAS

Abstract

The use of Eastman Kodak Chromagram® sheet for the separation of the various dyestuffs used in the compounding of inks has already been documented [1]. It has developed into one of the more useful techniques for the identification of inks. Both silica gel and cellulose Chromagram® sheets are now commonly used with a variety of eluent systems. Notwithstanding the variety of techniques available to the chromatographer, there are still certain mixtures of dyestuffs which do not yield clear-cut separations. The technique which will be reported here allows better separations to be made when used on these difficult mixtures.
