Characterisation of the Ionic Species of Iodine in Solutions of Na exp 123 I Using Instant Thin Layer Chromatography

摘要

A rapid and efficient method has been examined for characterising the ionic species of iodine present in carrier-free solutions of exp 123 I in very dilute sodium solution, prior to dispatch of the solution to the user for diagnostic and therapeutic purposes. A method based upon ascending instant thin layer chromatography using Gelman Seprachrom paper Type SG-ITLC and a developing solvent of n-butanol saturated with 3N NH sub 4 OH (1:1) has been found to be entirely satisfactory for this characterisation.
