Overview
The HG Series Hydrogen Generator is a CE-certified, Finland-engineered laboratory gas generation system designed specifically to replace high-pressure hydrogen cylinders in gas chromatography (GC) applications. It operates on the principle of proton exchange membrane (PEM) electrolysis of deionized water, producing ultra-high-purity hydrogen gas on-demand with zero reliance on compressed gas storage. This electrochemical process ensures continuous, stable H₂ output without combustion risk, volatile impurities, or pressure fluctuations—critical for baseline stability, peak resolution, and column longevity in analytical GC workflows. Unlike cylinder-based supply, the HG Series eliminates logistical constraints, regulatory handling requirements for Class 2.1 flammable gases, and potential contamination from valve wear or residual hydrocarbons in steel cylinders.
Key Features
- Ultra-high purity output: ≥99.9995% H₂ (5.5 N), upgradeable to ≥99.99999% (7.0 N) via optional integrated desiccant dryer
- Seven scalable flow models: HG-80 (0–80 mL/min) through HG-1500 (0–1500 mL/min), all with ±2% flow accuracy and <0.5% linearity deviation
- Real-time digital monitoring of H₂ pressure (0–7 barg), mass flow rate, internal leak status, and water level
- Automatic internal leak detection cycle performed at startup and during standby—compliant with IEC 61000-6-3 EMC standards
- Dual-stage drying architecture: built-in membrane dryer (dew point +15 °C) plus optional external cryo-absorption dryer (dew point −70 °C)
- Fail-safe operation: audible/visual alarms for low water level, electrolyte degradation, overpressure, and membrane integrity loss
- Modular design with external reservoir tank (quick-connect 5/16″ tubing), front-panel mode selector (Operate / Standby / Leak Test), and rear-panel remote I/O interface (dry contact alarm outputs & 0–10 V analog flow signal)
- Optional parallel operation module enables synchronized output from two units for redundancy or increased capacity—supports load-balancing and automatic switchover on fault detection
Sample Compatibility & Compliance
The HG Series is compatible with all major GC platforms requiring carrier-grade hydrogen, including Agilent, Thermo Fisher, Shimadzu, and PerkinElmer systems. It meets ISO 8573-1:2010 Class 1.1.1 for particulate, moisture, and oil content in compressed gases, and complies with EN 61010-1:2010 for laboratory electrical safety. Its PEM stack design conforms to ASTM D7622-21 for purity verification methodology in GC carrier gases. The system supports GLP/GMP environments through audit-ready event logging (power cycles, alarms, maintenance intervals) and optional firmware with FDA 21 CFR Part 11-compliant electronic signature and data integrity controls.
Software & Data Management
While the base unit operates via intuitive front-panel controls, optional PC software (HG-Link v3.x) provides full remote supervision—including real-time graphing of flow vs. time, historical alarm review, predictive maintenance alerts based on electrolyzer runtime and water consumption, and export of CSV-formatted operational logs. All firmware updates are delivered via encrypted USB stick; no internet connectivity is required during operation—ensuring network isolation for secure lab environments.
Applications
- Carrier gas for capillary GC and GC-MS systems requiring consistent, low-noise H₂ flow
- Fuel gas for flame ionization detectors (FID) and thermal conductivity detectors (TCD)
- Reduction atmosphere generation in hyphenated techniques such as GC-SCD or GC-AED
- On-site hydrogen supply for portable GC field instruments and mobile labs
- Research-grade synthesis support where trace O₂ or hydrocarbon contamination must be excluded (e.g., catalytic hydrogenation screening)
FAQ
What is the recommended feed water specification?
Deionized water with resistivity ≥15 MΩ·cm and total organic carbon (TOC) < 5 ppb is mandatory. Tap water or distilled water will damage the PEM membrane and void warranty.
Can the HG Series be integrated into a centralized lab gas network?
Yes—via optional manifold kits with pressure-regulated distribution lines and individual shutoff valves per instrument. Requires consultation with certified gas system engineers for ASME B31.3-compliant installation.
How often does the electrolyte require replacement?
The PEM stack uses solid polymer electrolyte with no liquid KOH; therefore, no periodic electrolyte replenishment is needed. Lifetime is rated at ≥15,000 operating hours under nominal load.
Is certification available for use in explosion-hazardous areas (ATEX/IECEx)?
Standard units are rated for Zone 2 / Class I Div 2. ATEX-certified variants (II 2G Ex db IIB T4 Gb) are available upon special order with modified enclosure and purge interlocks.
What maintenance is required annually?
Annual service includes membrane integrity test, sensor calibration verification, dryer cartridge replacement (if equipped), and firmware validation—performed by authorized service technicians using factory-traceable calibration standards.
