has function measure function pulsed amperometric detector A chromatography detector as used by high-performance anion exchange chromatography that provides sensitive and specific detection of carbohydrates. Pulsed Electrochemical Detection (PED) allows simple, sensitive, and direct detection of numerous polar aliphatic compounds, especially carbohydrates. This technique exploits the electrocatalytic activity of noble metal electrode surfaces to oxidize various polar functional groups. In PED, multi-step potential-time waveforms at Au and Pt electrodes realize amperometric/coulometric detection while maintaining uniform and reproducible electrode activity. The response mechanisms in PED are dominated by the surface properties of the electrode, and, as a consequence, members of each chemical class of compounds produce virtually identical voltammetric responses. Thus, the full potential is realized when combined with high performance liquid chromatography (HPLC).
