ELECTROCHEMISTRY FLOW CELL *

• SPR slide acts as working electrode
• Two insulated hollow tubes for counter and reference electrodes
• Slide replacement with easy quick-lock mechanism
• The whole assembly of the SPR slide can be kept under liquid to avoid contact with air!
• Top of the cuvette is open for pipeting enabling the change of the analyte!
• By utilizing the built-in two channel peristaltic pump, a continuous liquid flow through the cuvette can be arranged.

Highlights:

• EC working electrode: SPR sensor surface (e.g. Au)
• EC counterelectrode and reference electrode: easily exchangable wire e.g. Pt, Ag/AgCl, and others

Modes:

• SPR and EC measurements in parallel (increase in accuracy compared to separate measurement set-up)
• EC used as a stimuli

Why SPR Navi for EC measurements?

SPR Navi is especially useful for metals and other highly absorbing materials, which have a non-linear SPR response, because SPR Navi is based on a Multi-Parametric Surface Plasmon Resonance technique (MP-SPR) and measures the full SPR curve and not just a sensogram

Materials: 

Suitable for organic, inorganic or hybrid conductors and insulators

Applications (application note AN#120)

• Characterization of above materials
• Quality control / monitoring of depositions of above materials
• Detection of trace metals
