title: Stannous-ion quantitation in pyrophosphate and polyphosphate radiopharmaceutical kits using differential pulse polarography.
abstract: Stannous salts are used as reducing agents in many radiopharmaceutical kits. Differential pulse polarography, with 1 M sulfuric acid as the supporting electrolyte, is a relatively simple and effective technique for stannous quantitation and can be used in the quality assurance testing of pyrophosphate and polyphosphate radiopharmaceutical kits.
