title: Differential plus polarographic determination of submicrogram quantities of carmustine and related compounds in biological samples.
abstract: A polarographic method was developed to determine the antineoplastic agent carmustine and other nitrosoureas, such as N-methyl-N-nitrosourea and N-cyclohexyl-N-nitrosourea, in biological fluids at levels well below 1 microgram/ml or g. The stability of carmustine in different media was investigated to prevent losses during administration or assay. Examples of nitrosourea determination in biological samples are given.
