<p>A precious metal assay method which includes the steps of forming an electrolytic cell 201 comprising an anode specimen 106 and a reference cathode 112, driving a ramp input into the electrolytic cell 201, measuring a resulting current through the electrolytic cell 201 over a period of the ramp input. The assay value may be determined by comparing the locality or slope of an input current response of the resulting current against the localities or slopes of a list of regions of known precious metal compositions from an empirical look-up table and displaying the assay value on an electronics display 270.</p> |
