Overview
The Metrohm DropSens μStat-i MultiX is a high-performance, modular multi-channel electrochemical workstation engineered for precision electroanalytical research and industrial quality control. Based on bipotentiostatic architecture with integrated MultiplEIS® technology, it functions simultaneously as a potentiostat, galvanostat, and frequency-resolved impedance analyzer—enabling comprehensive characterization of electrode kinetics, interfacial charge transfer, double-layer capacitance, and bulk solution resistance. Designed for laboratory environments requiring parallel experimentation, the system supports up to 16 fully independent electrochemical channels housed in a single compact chassis. Each channel operates autonomously with dedicated analog front-end circuitry, eliminating crosstalk and ensuring measurement integrity across concurrent experiments—including cyclic voltammetry (CV), linear sweep voltammetry (LSV), chronoamperometry (CA), chronopotentiometry (CP), and multi-frequency EIS. Its architecture conforms to fundamental electrochemical instrumentation standards, including IEEE 1139 for signal fidelity and IEC 61000-4-3 for electromagnetic compatibility in analytical lab settings.

Sample Compatibility & Compliance
The μStat-i MultiX is optimized for use with screen-printed electrodes (SPEs), microelectrodes, conventional three-electrode cells (WE/RE/CE), and custom sensor arrays. Its low-noise analog design ensures reliable detection down to sub-nanoampere currents—critical for biosensor development, corrosion monitoring, and battery electrolyte analysis. The system complies with ISO/IEC 17025 requirements for calibration traceability and supports audit-ready operation under GLP and GMP frameworks. Firmware implements secure user authentication, electronic signatures, and full audit trail logging aligned with FDA 21 CFR Part 11 expectations for regulated laboratories. All electrical safety certifications meet IEC 61010-1:2012 for measurement, control, and laboratory equipment.
Software & Data Management
Operation is managed via DropView 3.0 software—a platform-certified Windows application supporting method scripting, real-time visualization, and automated batch processing. Each channel maintains discrete configuration profiles, allowing simultaneous execution of heterogeneous techniques (e.g., CV on Channel 1 while performing EIS on Channel 5). Raw data are stored in open-format .dvs files containing metadata (timestamp, operator ID, instrument serial, calibration history) and adhere to ASTM E2500-21 guidelines for digital data integrity. Export options include CSV, MATLAB (.mat), and Origin-compatible formats. Optional integration with LabArchives ELN and Thermo Fisher SampleManager LIMS enables end-to-end traceability from experiment initiation to regulatory submission.

- Corrosion rate mapping across alloy libraries under simulated service conditions
- Enzyme kinetics modeling via mediated electron transfer at modified electrode surfaces
- Quality assurance testing of electroplating baths and passivation solutions
- Academic teaching labs requiring scalable, student-safe instrumentation with role-based access control
FAQ
Can the μStat-i MultiX perform true simultaneous EIS on all 16 channels?
Yes—each channel contains a dedicated digital signal processor and analog-to-digital converter, enabling concurrent frequency-swept EIS acquisition without time multiplexing.
Is external shielding required for low-current measurements?
No—the instrument features built-in Faraday cage design and guarded input stages; however, use of shielded coaxial cables and grounded electrode holders is recommended for sub-100 pA work.
Does DropView support custom script-based automation?
Yes—Python API integration is available through the DropView SDK, permitting programmatic method generation, real-time data streaming, and third-party instrument synchronization.
What calibration standards are supported?
Factory calibration is traceable to NIST SRM 3100 series resistors and certified voltage references; users may perform two-point current/potential verification using DropSens Calibration Kits (Cat. No. CAL-01–CAL-04).
How is data security enforced during multi-user operation?
Role-based permissions (Administrator, Technician, Viewer) govern method editing, data export, and system configuration; all actions generate timestamped entries in an immutable audit log compliant with 21 CFR Part 11 Annex 11 requirements.
