A sensitive, alternative method to titrimetry or spectrophotometry for the evaluation of tin(I1) ions (O-5 pg ml-') in matrices containing tin(IV) ions was investigated. Differential pulse polarography was chosen. The supporting electrolyte was a buffer solution 0.7 M NaF/O.l M NaNOJ0.1 M HEPES at p
