Pulsed amperometric detection (PAD) is applicable for the quantitative detection of numerous organic compounds that adsorb at noble metal electrodes but cannot be detected satisfactorily by conventional amperometry at constant (dc) applied potential. A multistep waveform is applied in PAD with chrono‐amperometric detection based on faradaic signals, which frequently are produced by surface‐controlled reactions. We briefly review applications of PAD for liquid chromatography and present a unified explanation of the various modes of anodic response.
