Abstract : The dual electrode electrochemical detector has greatly enhanced high pressure liquid chromatography/electrochemical detection (HPLC/EC) capability. The most fruitful mode of operation is in the dual parallel electrode configuration. The ability to assess peak purity in real samples is very beneficial. Simultaneous recording of cathodic and anodic chromatograms to look possible impurities and munition decomposition products is an added technique to ascertain sample purity. The extent of electrode crosstalk can be minimized by repeating the experiment with the Au/Hg electrode OFF. In view of the low collection efficiencies encountered, the dual series mode of operation, at present, is of limited practical value for these types of electroactive substances.
