Development of a confined wall-jet flow-through cell for simultaneous electrochemical and surface plasmon resonance applications

摘要

A flow-through cell of the confined wall-jet type for electrochemical surface plasmon resonance (ESPR) applications has been developed. The geometrical cell volume of the electrochemical (EC) detection is adjusted to the surface plasmon resonance (SPR) cell volume by Reducing the electrode diameter. An electrode diameter of 3 mm gives the best similarity of the SPR and EC responses, using Hexacyanoferrate(II) in a flow-injection analysis (FIA) setup. Further hydrodynamic characterization is done by continuous-flow analysis.
