Hanon T930 Fully Automated Karl Fischer Coulometric & Volumetric Moisture Titrator

Overview

The Hanon T930 Fully Automated Karl Fischer Moisture Titrator is engineered for high-precision volumetric Karl Fischer titration in regulated laboratory environments. It operates on the stoichiometric reaction between iodine, sulfur dioxide, water, and a base in methanol-based electrolyte—enabling quantitative determination of water content in solids, liquids, and gases across pharmaceutical, petrochemical, food, cosmetic, and polymer industries. Unlike coulometric systems optimized for trace moisture (<100 ppm), the T930 employs dual-mode volumetric delivery with adaptive PID-controlled reagent dosing, delivering robust performance from 0.001% to 100% water content. Its architecture integrates electrochemical endpoint detection via bipotentiometric (dual-platinum electrode) polarization monitoring, where real-time current response to iodine concentration changes defines the equivalence point. The system supports both direct titration and oven-coupled headspace analysis—making it suitable for volatile, viscous, or thermally labile samples that cannot be introduced directly into the titration cell.

Key Features

• Fully automated volumetric Karl Fischer titration with closed-loop PID algorithm for dynamic reagent delivery (0.02 µL/s to 0.1 mL/s), minimizing overshoot and optimizing endpoint reproducibility.
• 10-inch high-resolution capacitive touchscreen interface running an embedded Android OS—designed for intuitive navigation, gesture-based data scrolling, and context-sensitive parameter editing without keyboard input.
• Modular software architecture with tabbed workflow menus enabling rapid access to method setup, real-time titration monitoring, calibration tools, and audit log review.
• Real-time graphical display of E-t (potential vs. time), V-t (volume vs. time), and E-V (potential vs. volume) curves—with pinch-to-zoom functionality and manual baseline adjustment.
• Integrated reagent management system: sealed, light-shielded burette with protective outer sleeve; plug-in reagent bottle holder accommodating 250 mL, 500 mL, and 1 L bottles; automatic solvent exchange without opening the titration vessel.
• Comprehensive safety engineering: waste overflow prevention, fume containment, and full isolation of operators from KF reagents during maintenance, refilling, and waste disposal.
• Multi-level endpoint logic selection—including relative drift stop, absolute drift stop, time-limited termination, and delayed confirmation—to accommodate challenging matrices such as hygroscopic powders, emulsions, or low-conductivity solvents.

Sample Compatibility & Compliance

The T930 accommodates diverse sample types through optional accessories: the T9301 heated headspace sampler (50–300 °C, ±1 °C accuracy, 5-segment programmable ramping) and the T9340 40-position automated sample handler with integrated oven coupling and inert gas purging (N₂ or air, 0–200 mL/min, ±2 mL/min accuracy). All components comply with ISO 760, ASTM E203, and USP for volumetric KF methodology. The instrument meets FDA 21 CFR Part 11 requirements through built-in electronic signature support, four-tier role-based access control (Super Administrator, Supervisor, Operator, IT Support), immutable audit trails with timestamped operator actions, and automatic backup to USB or network storage. Data integrity is further reinforced by tamper-evident file encryption and checksum validation for all stored methods, results, and calibration records.

Software & Data Management

The embedded firmware provides native support for GLP/GMP-aligned workflows, including method validation templates, blank correction protocols, titer standardization wizards, and drift compensation routines. All measurement data—including raw electrode signals, titrant consumption logs, temperature profiles (when coupled with T9301/T9340), and user annotations—are stored in a structured SQLite database within the 8 GB internal flash memory. Export options include CSV-compatible Excel (.xlsx) and digitally signed PDF reports containing metadata (instrument ID, operator ID, method version, environmental conditions). Remote diagnostics and firmware updates are supported via Wi-Fi or Ethernet, while RS-232 and BNC interfaces enable integration with LIMS and third-party process controllers. Automatic daily backups can be scheduled to external USB drives or cloud-synced NAS endpoints.

Applications

The T930 delivers validated performance in QC/QA laboratories requiring regulatory-grade moisture quantification. Typical applications include residual solvent analysis in active pharmaceutical ingredients (APIs), water content verification in lithium battery electrolytes, moisture profiling of hydrophilic excipients (e.g., microcrystalline cellulose, lactose monohydrate), and quality control of jet fuel per ASTM D6304. In polymer manufacturing, it measures bound water in polyamide resins prior to extrusion; in food science, it verifies moisture levels in dried dairy powders and roasted coffee beans. When paired with the T9340 autosampler, it enables unattended batch analysis of up to 39 samples—ideal for stability studies, release testing, and incoming raw material inspection.

FAQ

Does the T930 support both volumetric and coulometric Karl Fischer methods?
No—the T930 is a dedicated volumetric Karl Fischer titrator. For coulometric applications, Hanon offers the complementary T931 Coulometric Moisture Analyzer, which shares compatible accessories and software architecture.
Can the T930 be validated for GMP compliance?
Yes. The system includes IQ/OQ documentation templates, 21 CFR Part 11-compliant audit trails, electronic signatures, and configurable permission sets required for GMP-regulated environments.
What is the minimum detectable water mass using the T930?
At optimal sensitivity settings and with 5 mL burette configuration, the theoretical lower limit is approximately 10 µg H₂O (equivalent to ~0.001% in a 1 g sample), subject to sample homogeneity and background drift control.
Is method transfer possible between the T930 and other Hanon titrators?
Yes—method files (.hmf) are cross-compatible with T931 and T9340 platforms, enabling seamless migration of validated procedures across volumetric and coulometric workflows.
How does the T930 handle high-viscosity or particulate-laden samples?
It supports optional syringe-based injection kits and heated headspace sampling (T9301/T9340), eliminating direct contact between sample matrix and titration cell while maintaining quantitative recovery and endpoint clarity.
