Inverse-voltammetric determination of bismuth in biomaterials with computer assisted peak evaluation

Summary

The accuracy of the peak evaluation in inverse-voltammetric determinations depends of the kind of baseline approximation in the peak area. For the inverse-voltammetric determination of bismuth the best baseline extrapolation is done by a 3rd order hyperbola. Using this kind of baseline-approximation the evaluation error of the bismuth determination in the range of μg/l can be reduced from more than 10% to less than 3%.
