Pulsed Amperometric Detection (PAD)
With Pulsed Amperometric Detection a series of pulses (pulse profile) is periodically repeated. Pulsed Amperometric Detection can be used when higher sensitivity is required. Using pulses instead of constant potential might result in higher faradaic currents. PAD is also used when the electrode surface has to be regenerated continuously, for instance, to remove adsorbents from the electrode surface.
