Software & Analysis
- CS Studio 6.0: user-defined test sequences and real-time data saving.
- Data analysis: CV peak/integration analysis, Tafel fitting, equivalent-circuit EIS fitting, electrochemical noise and Mott–Schottky analysis.
- Battery analysis: capacity, specific capacitance, efficiency and charge/discharge energy.
- SDK: integration examples and interfaces for Python, LabVIEW, C, C++, C# and related languages; confirm the supplied SDK package.
- Export: data formats compatible with OriginPro and Microsoft Excel.
Optional Expansion
- Current boosters: CS2020B / CS2040B / CS2100B are described for expansion to ±20 A / ±40 A / ±100 A. These are external options, not the standard CS350M current rating.
- Custom compliance: ±30 V is described as a custom single-channel option; confirm availability for the ordered configuration.
- Multiplexer: 16–32-channel expansion is described for sequential high-throughput work; it is not equivalent to independent simultaneous potentiostat channels.
- CST520 electrode mapper: compatibility is described for the CS family; confirm configuration and accessories for CS350M.
Configuration & Enquiry
- Specify the cell configuration, required potential/current range and impedance bandwidth when requesting a quotation.
- Confirm the current document revision, selected accessories and calibration information.
- The model-specific specification table is used here. Broader CS-family passages contain different sensitivity, resolution and impedance claims; these have not been substituted into the CS350M table.
Prepared from the supplied seven-page CS350M document. Specifications and optional configurations require confirmation for the supplied instrument.
