The nature of two technetium-labeled radiopharmaceutical components has been established by means of fast-atom-bombardment mass spectrometry (FABMS) in combination with carrier-added (CA) and no-carrier-added (NCA) reversed-phase high-pressure liquid chromatography (HPLC). Negative-ion FABMS was used to determine that the epimers of Tc-CO2DADS are the oxo(N,N'-(1-carboxyethylene)-bis-(2-mercaptoacetimido))technetate(V) ions; positive-ion FABMS showed that Tc-HIDA is bis(N-(2,6-dimethylphenyl-carbamoylmethyliminodiaceto)technetate(III).
