TL;DR: The dropping mercury electrode can be used for oscillo-polarography as mentioned in this paper, but it is often difficult to interpret the results of such a procedure, and it is not suitable for the analysis of organic compounds.
Abstract: THE dropping mercury electrode can be used for oscillo-polarography1 but the oscillo-polarograms obtained during the investigation of organic compounds are often difficult to interpret.

TL;DR: In this paper, the use of modern polarographic and voltammetric techniques for the determination of selected carcinogenic nitro and amino derivatives of polycyclic aromatic hydrocarbons is discussed.
Abstract: Nitro and amino derivatives of polycyclic aromatic hydrocarbons (NPAH and APAH) are well-known chemical carcinogens which should be carefully monitored in our environment. So far, mostly HPLC methods are used for these purposes, while polarographic and voltammetric methods are used less frequently. This article deals with the use of modern polarographic and voltammetric techniques (namely differential pulse polarography, differential pulse voltammetry, adsorptive stripping voltammetry and HPLC with electrochemical detection) for the determination of selected carcinogenic nitro and amino derivatives of polycyclic aromatic hydrocarbons. Optimum conditions are described for the determination of nanomolar or subnanomolar concentrations of nitro derivatives using mercury electrodes and for the determination of submicromolar concentrations of amino derivatives using solid or carbon paste electrodes or HPLC with electrochemical detection. The selectivity of all these methods can be improved by preliminary separation using liquid–liquid or solid phase extraction.

TL;DR: In this article, the amount of mercury, deposited on a glassy carbon electrode at various potentials during the first 200 ms of electrolysis, has been determined by constant current coulometric stripping potentiometry.
