New Multi-Channel Electrochemical Impedance Analyzer

Uniscan Instruments has introduced the Model 3300 multi-channel electrochemical impedance analyzer. The Model 3300 is a new generation of instrumentation with the FRA and potentiostat mounted on a standard format card rack. This modular approach allows plug-in expansion capability.

Uniscan’s hybrid 32 bit DAC technology creates ultra smooth voltammetry waveforms with precise digital control which provide the versatility and performance required for electrochemical applications in a multi-channel format.

Research application areas which will utilize the capabilities of the Model 3300 multi-channel electrochemical impedance system include: -

• Materials characterization
• Electrodeposition studies
• Combinatorial electrochemistry
• Fuel-cell catalysts
• Corrosion
• Energy storage
• Sensor development / Q.C.
• Research Electrochemistry

The Model 3300 multi-channel electrochemical impedance analyzer has excellent low current performance. It combines a wide dynamic range with ultra low current capability for demanding applications in nano-technology, microelectrode, and sensor applications without the requirement for optional plug-in low current amplifiers.

The higher standard current capability and compliance voltage allows the Model 3300 to be used in a wide range of demanding applications such as corrosion, fuel cell and energy storage.

The latest versions of the UiEChemTM and UiECorrTM software packages support the 3300 multi-channel electrochemical impedance analyzer and provide a wide range of electrochemical impedance techniques. These include: -

• Single sine, swept frequency (Lin or Log steps)
• Impedance vs. time
• Mott Schottky multi frequency, step potential
• Galvanostatic Impedance
• Impedance cell modelling with the internal software

UiEChemTM also provides techniques used by research electrochemists such as cyclic voltammetry, chronoamperometry and square wave voltammetry whilst UiECorrTM provides dc techniques such as LPR, Tafel and Potentiodynamic Polarisation for use by materials scientists.
