nature : a polarography. The pulse polarography, every drop of mercury dropping by adding a few dozen milliseconds wide square wave pulse voltage pulse in the latter half of current records. According to the Canadian voltage in a different way, the pulse polarography are two basic forms : conventional pulse polarography (normal pulse polarography; NPP) and differential pulse polarography (differential pulse polarography; DPP). The former joined the pulse amplitude over time increased linearly, intermittent pulse during the same potential starting potential; The latter is joined each pulse amplitude and pulse rate of those in a linear superposition changes in the scanning voltage above. Pulse Polarography can effectively overcome the capacitance and current measurement noise on the capillary Faraday current interference, which is the highest sensitivity of a polarography, higher resolution. The law, in addition to analysis of the application, the electrode can be used to study the mechanism, such as the judgment reversible process, discriminant various polarographic current nature, such as determination of kinetic parameters.
