3465 Electrochemical Detector for LC Systems
Sensitivity, reliability, and simplicity combined
The Waters 3465 Electrochemical Detector combines sensitivity, reliability, and simplicity for electrochemical detection. Its versatile detection modes are ideally suited for analyzing a wide range of compounds.
The 3465 Electrochemical Detector’s multiple flow cell configuration combines working and reference electrode designs to minimize cost and enhance flexibility. The flow cell accommodates several reference electrodes: ISAAC; traditional salt-bridge design, which limits air bubble formation; and Hy-Ref, which is ideal for carbohydrate analysis and is compatible with extreme mobile phases. The detector is designed for ultra-trace analysis and is compatible with both analytical and microbore scale applications.
