A measurement technique is examined that served to investigate the low frequency conductance of electrolyte solutes. The set-up, analyzed on the basis of its equivalent circuit, shows major deficiencies, which actually caused the observed frequency dispersion and the presumed inductive behaviour. The problem, basically, is due to the use of non-contacting electrodes for signal in/out coupling, in combination with a capillary flow cell as sample holder. (C) 2009 Elsevier B.V.
