Abstract

An ion chromatographic technique was used to analyze (sodium) thiosulfate in photographic gelatin. A specially prepared anion exchange resin of very low capacity was used as a packing material of a concentrator column. and a separating column. Thiosulfate ion was first concentrated in a concentrator column by flowing the aqueous solution of photographic gelatin, and then thiosulfate was eluted by appropriate eluent and detected with a conductivity cell. This was found to be very simple method to analyze thiosulfate in gelatin.
