Potentiometric stripping analysis and constant current stripping analysis a
re proposed as routine methods for analysis of copper, zinc and selenium in
plasma and urine samples. The analytical performance of these methods is c
omparable with that reported for atomic absorption spectrometry. However th
e low cost, greater simplicity of the apparatus, and the facility of execut
ion make this methodology a valid candidate for routine application in Clin
ical Chemistry laboratories. (C) 1999 Elsevier Science B.V. All rights rese
