## Abstract __Background__: The European Pharmacopoeia and radiopharmaceutical manufacturers specify Instant Thin‐Layer Chromatography Silica Gel impregnated glass fibre (ITLC‐SG) as the stationary phase for measuring the radiochemical purity (RCP) of most technetium‐99m (^99m^Tc) radiopharmaceutic
