ABSTRACT:
In operating an ECD in constant current mode, two pulses are implemented either to the same electrode or to separate electrodes, thereby dispersing the space charge sheath near the collector electrode and thus enhancing electron extraction at high frequencies. This has the effect of extending both the dynamic range and the linear dynamic range.
