Differential pulse polarographic determination of 2,3-dimercaptosuccinic acid and tin (II) in radiopharmaceuticals.
A differential pulse polarographic procedure was developed for the assay of dimercaptosuccinic acid and tin(II), components of a commercially available pharmaceutical kit for kidney scintigraphy. The method is quantitative and qualitative for both the chelated and unchelated forms of dimercaptosuccinic acid and tin(II) in a mixture of the two.
