Abstract:

Capillary electrophoresis with amperometric detection(CE/AD) is a highly efficient and sensitive technique capable of separation and determination of charged analytes in ultrasmall-volume samples. However, the extension of CE/AD application was limited due to the requirement for the analytes inherently possessing electroactivity. Several approaches have been proposed to improve the applicability of the technique such as indirect detection, sample derivatization and utilization of a variety of chemically modified electrodes.
