与液相色谱一起使用的双电化学检测器可显示选择性、灵敏度和宽动态范围。它表现出约 105 的线性范围，同时能够感测某些物种的亚皮摩尔量。此外，仅检测那些在选定电位下表现出电活性（氧化或还原）的化合物。双检测器提供两种独特的操作模式。对于色谱重叠但具有不同电化学形式电位的化合物，该系统提供仪器分离。对于常规调查，该系统可以显着减少时间，而不会导致成本成比例增加。
Selectivity, sensitivity, and wide dynamic range are all displayed by the dual electrochemical detector for use with liquid chromatography. Exhibiting a linear range of about 105, it is, at the same time, capable of sensing sub-picomole quantities of certain species. Moreover, only those compounds which display electroactivity (oxidation or reduction) at the chosen potential(s) are detected.Two distinctive modes of operation are available with the dual detector. For compounds which overlap chromatographically, but have differing electrochemical formal potentials, the system offers an instrumental separation. For routine investigations, the system provides significant time reductions without causing proportionate increases in cost.
