Loveland and Elving observed four capacity peaks on the differential capacitance curves obtained by the oscillographic method. The two outer peaks were considered to be due to the complete desorption of alcohol molecules from the electrode surface, while the two inner ones were explained in terms of the removal of a second layer of adsorbed molecules which, at small electrode charges, form a micellar film [3]. 

An oscilloscope instead of a galvanometer is often used to follow rapid reactions occurring during the life of a single drop. There are two main groups of oscillographic methods used for the study of... 

The method, as so far developed, is limited by the condition that the hydration-dehydration reaction must proceed at a rate that is slow compared with the time needed to obtain a polarogram. In principle, the method is capable of much wider application to covalent-hydration studies if use is made of oscillographic polarographic techniques or of chronopotentiometry. These refinements are currently being investigated.

In transient measurements one must record rapidfy changing currents or potentials. In the past, cathode-ray oscilloscopes have been used for this purpose (at present, improved recording devices or computers are used as well), hence the term oscillographic polarography (or oscillographic voltammetry). This term is unfortunate since it reflects only the device used to record the results, rather than the essential features of the method used for the measurements. 

CA 55, 17007 (1961) [A new method has been described, based on measuring the electromotive force in a conductor moving in a magnetic field with expln products. A Cu or Al foil 0.3-0.5 mm thick was used as the conductor, the emf being recorded by means of a cathode-ray oscillograph, and the speed (u) being ealed from the equation u = (r/Hl) x 10 cm/sec...

The determination of detonation velocity is based upon measurement of the time interval needed for the detonation wave to travel a known distance through the explosive under test. The methods used to determine VOD may be classified as mechanical methods (Dautriche method), electrical methods [pin oscillographic technique (POT)], optical methods and radiographic methods. The methods which are generally used for the determination of VOD are ...

Chrono amperom etry, Chronopotentiometry, Chronopolarography and Oscillographic Pol orography. A "steady state is said to be reached when the current-potential curve of a soln examined by the usual electrochemical methods (such as potentiometric titration, voltammetry, etc) becomes independent of time (at least for the period of time needed to carry out the measurements). However there are electrolitic phenomena which change with time,resulting in the existence of an unsteady...
