Direct current polarization test

When mercury is used as the electrode in the form of small drops falling slowly from a fine capillary tube in the test solution, the technique has the special name polarography. This name is derived from the fact that the electrode can be polarized. An electrode is said to be polarized when no direct current flows across its interface... 

A major fallacy is made when observations obeying a known physical law are subjected to trend-oriented tests, but without allowing for a specific behaviour predicted by the law in certain sub-domains of the observation set. This can be seen in Table 11 where a partial set of classical cathode polarization data has been reconstructed from a current versus total polarization graph [28], If all data pairs were equally treated, rank distribution analysis would lead to an erroneous conclusion, inasmuch as the (admittedly short) limiting-current plateau for cupric ion discharge, albeit included in the data, would be ignored. Along this plateau, the independence of current from polarization potential follows directly from the theory of natural convection at a flat plate, with ample empirical support from electrochemical mass transport experiments. 

A further modification addresses a remote loophole for local realism in which the polarization detectors might somehow be able to signal one another at subluminal speed. Aspect designed an experiment in which mirrors switched at high speed could direct the two photons to different detectors, after they were already inflight. It was verified in this "delayed choice experiment that Bell s inequality is still violated, in what is currently considered the most conclusive test of nonlocality.
