Product Overview
This analytical moisture determination system combines an advanced coulometric Karl Fischer titrator with an automated headspace thermal extraction oven to deliver high-precision trace moisture quantification. Engineered specifically for challenging solid and liquid matrices, the combined apparatus isolates moisture from insoluble or chemically reactive matrices by thermally extracting volatile water vapor directly into a sealed titration cell via a dry carrier gas stream. This dual-unit configuration eliminates side reactions, prevents matrix fouling of the titration reagents, and provides microgram-level detection accuracy essential for advanced materials characterization.
Designed primarily for energy storage research, battery manufacturing, fine chemical production, and quality assurance laboratories, the equipment excels in testing battery cathode and anode powders, separator membranes, and organic liquid electrolytes. By integrating direct coulometric titration capabilities with automated headspace heating, researchers and quality managers can seamlessly transition between pure liquid samples and complex solid compounds without manual reagent contamination or tedious extraction protocols.
Built for high-throughput testing environments, the instrumentation features robust digital control systems, precision heating blocks, and rigorous electronic titration algorithms that maintain reproducible baseline stability. Full compliance with strict Good Laboratory Practice (GLP) and ISO 900x protocols ensures complete data traceability and audit readiness, delivering absolute measurement integrity across continuous industrial operating shifts and mission-critical research cycles.
Key Features
- Integrated Coulometric Titration Cell: High-sensitivity coulometric generation system measures trace water content down to 10 micrograms with exceptional electrochemical precision and drift compensation.
- Automated Headspace Thermal Extraction: Sealed-vial sample heating processor transfers liberated moisture directly to the titration vessel via controlled carrier gas, preventing insoluble solids from fouling electrolyte reagents.
- Real-Time Dynamic Moisture-Time Graphing: Integrated full-color touchscreen interface plots real-time extraction and titration curves, enabling operators to observe reaction kinetics and optimize heating profiles instantly.
- Comprehensive GLP/ISO Compliance Statistics: Automated software modules calculate mean values, absolute standard deviations, and relative standard deviations (RSD) to satisfy stringent quality auditing protocols.
- High-Speed Quantitative Performance: Rapid electrolytic titration capability handles moisture measurement rates up to 2.24 mg of water per minute, accelerating overall batch testing cycle times.
- Direct Analytical Balance Interfacing: Dedicated digital communication port connects to external laboratory balances to transfer sample weight data automatically, eliminating manual transcription errors.
- Independent Thermal and Flow Controls: Front-panel digital regulation provides precise control over extraction heating temperatures and carrier gas flow rates for optimized outgassing parameters across varied sample types.
- Compact Dual-Unit Modular Architecture: Space-efficient footprint allows flexible benchtop arrangement while maintaining thermal separation between the high-temperature oven and sensitive coulometric titration glassware.
Applications
