A dummy cell for differential-pulse polarographic analysers.
A non-linear network is proposed for simulating the response of electrochemical cells in differential-pulse polarographic (DPP) analysis. The response of a DPP analyser connected to the dummy cell is a bell-shaped current peak (I(p)) located at any desired point along the potential-scan range. Approximate model calculations of the expected I(p), as a function of the dummy-cell parameters are in good agreement with measured data. It is suggested that the dummy cell could be useful in the analytical laboratory and during studies for improving DPP analysers.
