An electrochemical preconcentration and separation capacity has been developed for conventional inductively coupled plasma emission spectrometers. The preconcentration is achieved by electroplating the sample onto a graphite electrode of spectral grade purity. The step also serves to separate the desired element. It was found that separate precoating with mercury significantly enhanced the analysis. The detection limit for copper was found to be as low as 0.7 ng/mL.
