Zennium XC

Compact high-end electrochemistry for AC + DC measurements

The ZAHNER ZENNIUM XC is a compact, laboratory-grade potentiostat/galvanostat with an integrated frequency response analyser (FRA) for electrochemical impedance spectroscopy (EIS). Like all potentiostats, it precisely controls the potential of the working electrode versus a reference electrode while measuring current via the counter electrode; in galvanostatic operation it controls current and measures the resulting potential response. This makes it a strong choice for modern electrochemistry, where both time-domain and frequency-domain information are required.

Key performance features (research-ready)

• EIS frequency range: 10 µHz to 5 MHz for slow diffusion processes through to high-frequency interface behaviour
• High current capability: up to ±2 A for demanding cells and low-impedance systems
• Compliance voltage options: ±5 V and ±14 V to support a broad range of electrochemical cells
• High-resolution measurement chain: 32-bit DC resolution and high dynamic AC capability for sensitive impedance work
• Switchable floating/ground modes to suit corrosion labs, grounded test stands, and noise-sensitive environments
• Advanced EIS options: support for multi-sine style excitations and non-linear impedance approaches (method dependent)
  
  

Compatibility and integration

ZENNIUM XC supports standard 2-, 3-, and 4-electrode configurations and integrates naturally with electrochemical cells (including corrosion cells and small-volume lab cells), battery test fixtures, and photoelectrochemistry add-ons. It can also be integrated into automated research workflows using common scripting/instrument-control approaches, making it suitable for multi-step experiments and long-duration durability testing.

Typical applications

• Battery research: kinetics, charge transfer, SEI/interface studies, equivalent circuit modelling
• Corrosion & coatings: polarisation methods, inhibitor screening, coating barrier performance (EIS)
• Electrocatalysis & sensors: mechanism studies, stability, impedance-based diagnostics
• Fuel cells/electrolysers (R&D scale): low-impedance and dynamic behaviour measurement
