摘要: A new design of a contactless conductivity detector for capillary electrophoresis is demonstrated the detection compounds relevance in metal plating baths. Galvanic baths deposition Zn, Cu, Ni and Ag were analysed. The related to zinc system contained Zn2+, Na+, Mg2+ NH4+, copper CuEDTA2−, SO42−, oxalate−, EDTA2− glyoxylate, nickel Ni2+, Co2+ NH4+ silver included AgCN−, NO3− CN−. Concurrent determinations could be carried out less than 10 min.
