The method of quotient of two waves can be applied in cases similar to those in which the simple calibration curve is used. Temperature control is unnecessary, but construction of several calibration curves for different concentrations of the pilot substance is usually necessary. [Pg.68]

The procedure known as quotient of two waves is independent of temperature. In this method a known quantity of a certain polarographically active substance is added to each solution in which another component is to be determined. It is assumed that the ratio of the two waves (for the unknown and for the added standard or pilot) is independent of temperature, viscosity, rate of flow of mercury etc. The calibration curves are constructed by plotting the ratio of the two waves against the concentration of the substance to be determined, keeping the concentration of the pilot constant. These calibration curves are used in the same way as the ordinary curves. [Pg.76]

The logarithmic decrement A, as a measure of the damping, can be defined as the logarithm of the quotient of the amplitude of two successive waves. Then [Pg.276]

The time interval needed for the detonation wave to travel the pre-determined distance between two probes is measured using built-in cursors of the oscilloscope. The detonation velocity is then calculated as a quotient of the distance between two probes(d) and corresponding time interval (t). Similarly the VOD is [Pg.201]

If two probes are inserted into an explosive charge at a known distance from each other (L the arrival of the detonation wave at the first probe will start the counting assembly while its arrival at the second probe will stop it. The time interval registered by the counting assembly (/) is the time needed by the detonation wave to pass the distance L. The detonation velocity is then calculated as the quotient of distance and time [Pg.106]
