Ivium CompactStat.h10800 Portable Electrochemical Workstation

Overview

The Ivium CompactStat.h10800 is a high-precision, single-channel portable electrochemical workstation engineered for rigorous laboratory and field-deployable applications requiring exceptional resolution, stability, and spectral breadth in potentiostatic, galvanostatic, and electrochemical impedance spectroscopy (EIS) measurements. Based on Ivium’s proprietary digital potentiostat architecture, the system employs a 24-bit dual DAC/ADC design with real-time digital signal processing to ensure minimal noise floor, ultra-low drift, and high reproducibility across all operating modes. Its core measurement principle relies on controlled potential/current application via feedback-controlled analog circuitry combined with oversampled digital acquisition—enabling accurate quantification of faradaic and non-faradaic processes in aqueous, non-aqueous, and solid-state electrochemical systems. Designed for compliance with fundamental electrochemical standards—including ASTM G59 (potentiodynamic polarization), ASTM G102 (electrochemical impedance analysis), and ISO 16773-2 (corrosion testing)—the CompactStat.h10800 serves as a foundational platform for corrosion science, battery R&D, sensor development, electrode kinetics studies, and fundamental interfacial electrochemistry.

Key Features

• Ultra-high current resolution: 0.00006% of full-scale range, down to 0.6 aA (attoampere) at the 1 pA range—enabling detection of sub-molecular electron transfer events in low-conductivity media.
• Precision potentiostatic control: ±10 V compliance range with 0.003% accuracy and <16 nV minimum potential step resolution, supporting both macro- and micro-electrode configurations.
• Broad dynamic EIS capability: 10 µHz to 3 MHz frequency sweep range with phase accuracy <0.1° and magnitude accuracy <0.02%—suitable for modeling charge-transfer resistance, double-layer capacitance, diffusion impedance, and distributed element networks.
• True portable architecture: Integrated lithium-polymer battery support (optional), IP54-rated enclosure, and USB-C powered operation enable reliable use in gloveboxes, fume hoods, or remote field sites without AC dependency.
• Hardware-based stability: Onboard temperature-compensated reference voltage source and active guard shielding minimize thermal drift and electromagnetic interference—critical for long-duration chronoamperometry or low-frequency impedance measurements.

Sample Compatibility & Compliance

The CompactStat.h10800 supports standard three-electrode cell configurations (working, counter, reference) and is compatible with common reference electrodes (Ag/AgCl, SCE, Hg/Hg₂SO₄), inert working electrodes (Pt, Au, GC, carbon paste), and custom micro/nanostructured interfaces. It meets mechanical and electrical safety requirements per IEC 61010-1 and EMC directive 2014/30/EU. For regulated environments, the instrument supports audit-trail-enabled data logging compliant with FDA 21 CFR Part 11 when used with IviumSoft v12+ and validated computer systems. All electrochemical methods adhere to ISO 17025 traceability frameworks through NIST-traceable calibration procedures performed at Ivium’s NL-MEA accredited facility in Eindhoven.

Software & Data Management

Controlled exclusively via IviumSoft—a Windows-native application certified for Windows 10/11 x64—the workstation delivers fully scriptable experiment sequencing, real-time FFT-based noise diagnostics, and automated Kramers–Kronig validation for EIS datasets. Raw data are stored in open-format .ivium binary files with embedded metadata (timestamp, operator ID, method parameters, calibration history). Export options include CSV, MATLAB (.mat), and ASCII-compatible formats suitable for third-party modeling tools (e.g., Thales, EC-Lab, Python-based impedance.py). Version-controlled method templates, user-role access levels, and encrypted project archives facilitate GLP/GMP-aligned workflows in QC laboratories and contract research organizations.

Applications

• Battery material characterization: Cycle-life-dependent SEI growth analysis via low-frequency EIS (<10 mHz), differential capacity (dQ/dV) mapping, and galvanostatic intermittent titration technique (GITT).
• Corrosion monitoring: Linear polarization resistance (LPR), electrochemical noise (EN), and harmonic distortion analysis for real-time assessment of inhibitor efficiency in oilfield brines or marine coatings.
• Biosensor development: Amperometric detection of enzymatic reactions (e.g., glucose oxidase), DNA hybridization kinetics, and redox-labeled aptamer binding under physiological ionic strength conditions.
• Fuel cell catalyst evaluation: Oxygen reduction reaction (ORR) activity quantification using rotating disk electrode (RDE) protocols, including Koutecky–Levich analysis and Tafel slope derivation.
• Electrodeposition process control: Pulse-reverse plating waveform synthesis, nucleation overpotential mapping, and in-situ monitoring of metal ion depletion zones during Cu or Ni deposition.

FAQ

What is the maximum current output capability of the CompactStat.h10800?

The unit supports up to ±800 mA continuous current output with full potentiostatic control, verified per Ivium’s internal test protocol IV-PS-007.
Does the system support true four-electrode (Kelvin) measurements?

No—it operates in standard three-electrode mode; however, external current-sensing shunts or bipotentiostat add-ons (e.g., Ivium StatBox) enable pseudo-four-terminal configurations for high-resistance electrolyte studies.
Is firmware upgrade available remotely?

Yes—firmware updates are delivered via IviumSoft’s integrated updater module and require no hardware modification or service intervention.
Can EIS data be acquired simultaneously with DC techniques?

Yes—hybrid methods such as galvanostatic EIS (GEIS) or potentiostatic EIS superimposed on cyclic voltammetry are supported through multi-step method scripting.
What calibration standards are recommended for routine verification?

Ivium recommends quarterly verification using certified resistor-capacitor networks (e.g., IET Labs RC-100 series) and NIST-traceable reference electrodes, documented in accordance with ISO/IEC 17025 clause 6.6.
