摘要：

A new design of a contactless conductivity detector for capillary electrophoresis is demonstrated for the detection of compounds of relevance in metal plating baths. Galvanic baths for the deposition of Zn, Cu, Ni and Ag were analysed. The compounds related to the zinc plating system contained Zn2+, Na+, Mg2+ and NH4+, the copper plating system CuEDTA(2-), SO42-, oxalate-, EDTA(2-) and glyoxylate, the nickel plating system Ni2+, Co2+ and NH4+ and the silver plating system included AgCN-, NO3- and CN-. Concurrent determinations of the compounds could be carried out in less than 10 min.
