Drop Time

The behaviour of electrochemically reducible single-strand polynucleotides (poly(adenylic acid)) and poly(cytidylic acid)) was studied by the differential (derivative) pulse polarography (DPP) and by other methods. Measurements were performed with the help of the dropping mercury electrode under various conditions specified by the pulse width, pulse amplitude, drop time etc. For the faradaic and tensammetric DPP peaks the diagnostic criteria were proposed which make it possible to classify even very small DPP peaks of double helical polynucleotides.

Dropping Mercury Electrode

The behaviour of perinaphthenone at the dropping mercury electrode has been investigated by the combined techniques of conventional (D.C.) and alternating current (A.C.) polarography. Two D.C. steps were observed, but an A.C. polarographic wave was found only at the potential of the more positive D.C. step. Two tensammetric waves were also seen, one of which appears to be the outcome of multilayer adsorption or of a change in state of the adsorbed film.

Polarographic Current

An equation for the A.C. polarographic current is derived from considerations of concentration changes produced at the dropping mercury electrode in virtue of the superposition of a small sinusoidal alternating voltage onto the direct potential, for the case of reversibly reduced inorganic ions. The equation predicts the magnitude of the A.C. polarographic current at any point on the polarogram.
