Voltametric analysis apparatus and method
An apparatus and method are disclosed for electrochemical analysis of elements in solution. An auxiliary electrode a reference electrode and five working electrodes are positioned in a container containing a sample solution. The working electrodes are spaced apart evenly from each other and auxiliary electrode to minimize any inter-electrode interference that may occur during analysis. An electric potential is applied between auxiliary electrode and each of the working electrodes. Simultaneous measurements taken of the current flow through each of the working electrodes for each given potential in a potential range are used for identifying chemical elements present in sample solution and their respective concentrations. Multiple working electrodes enable a more positive identification to be made by providing unique data characteristic of chemical elements present in the sample solution.
