Overview
The i-Lab HG200 Ultra-High-Purity Hydrogen Generator is an engineered solution for laboratories requiring continuous, on-demand hydrogen gas with exceptional purity and operational reliability. Utilizing solid polymer electrolyte (SPE) and proton exchange membrane (PEM) technology, the HG200 performs pure-water electrolysis—eliminating alkaline electrolytes entirely. This electrochemical process yields hydrogen gas at ≥99.9995% purity (5.5 N), with total hydrocarbon content <0.1 ppmv and oxygen content <0.5 ppmv—meeting stringent requirements for flame ionization detection (FID), nitrogen-phosphorus detection (NPD), and mass spectrometry ion sources. Designed for integration into analytical workflows where gas integrity directly impacts data fidelity, the HG200 delivers stable flow and pressure control across its full operating range (0–200 mL/min, 0–8 bar), ensuring compatibility with both benchtop GC systems and high-throughput GC-MS platforms.
Key Features
- SPE/PEM electrolysis core: No caustic electrolytes, no liquid maintenance, zero risk of carryover contamination to downstream instruments.
- Integrated pressure-regulated output: Maintains constant pressure or constant flow mode via closed-loop feedback control; eliminates need for external regulators or back-pressure valves.
- Intelligent automation: Fully automatic startup, self-diagnostic routines, real-time monitoring of cell voltage, temperature, and water level; one-touch operation via built-in LCD interface.
- Long-interval maintenance architecture: Integrated pressure-swing adsorption (PSA) dryer and catalytic oxygen scavenger ensure >12 months of filter-free operation under standard laboratory conditions.
- Low-noise, space-efficient design: Acoustic noise ≤55 dB(A); footprint under 280 × 420 × 450 mm (W × D × H); suitable for placement inside fume hoods or adjacent to GC instrument racks.
- Multilayer safety system: Dual-pressure sensor redundancy, hydrogen leak detection via semiconductor sensor (response time 8.5 bar), overtemperature (>65°C), or electrolyte depletion.
Sample Compatibility & Compliance
The HG200 is validated for use as a dedicated hydrogen source in regulated analytical environments. Its gas output complies with ASTM D7217–22 (Standard Specification for High-Purity Hydrogen for Analytical Instrumentation) and meets the trace impurity thresholds required by USP , ISO 8573-1 Class 1 (for particles, water, and oil), and IEC 61000-6-3 (EMC emissions). The unit supports GLP/GMP-aligned workflows through optional audit-trail-enabled firmware (with timestamped event logging), and its firmware architecture is compatible with FDA 21 CFR Part 11-compliant data management systems when deployed with validated LIMS integration.
Software & Data Management
The HG200 includes embedded Ethernet and RS-232 interfaces for bidirectional communication. Optional i-Lab ControlSuite™ software enables remote monitoring and control via secure HTTPS web interface or local network API (RESTful endpoints). Logged parameters include cumulative runtime, total H₂ output volume, cell efficiency metrics (V/A·L), and fault history with ISO 13849-1–aligned diagnostic codes. All logs are exportable in CSV format with UTC timestamps; configuration changes are recorded with user ID and IP address for accountability.
Applications
- GC detector fuel gas: Primary hydrogen supply for FID, FPD, and NPD detectors—ensuring consistent flame stability and baseline reproducibility.
- GC-MS carrier gas substitution: Replaces helium in hydrogen-based ion sources (e.g., EI, CI), reducing operational cost while maintaining resolution and sensitivity in volatile organic compound analysis.
- Calibration gas generation: On-site production of certified reference mixtures when paired with precision mass flow controllers and dilution manifolds.
- R&D and industrial applications: Supports hydrogen-sensitive processes in semiconductor wafer annealing, fuel cell catalyst testing, and isotopic labeling studies requiring ultra-low O₂ and H₂O background.
FAQ
What water quality is required for optimal operation?
Deionized water with resistivity ≥15 MΩ·cm and TOC <10 ppb is recommended. Internal conductivity monitoring triggers alerts if feedwater purity degrades beyond specification.
Can the HG200 be integrated into a centralized lab gas network?
Yes—via optional manifold-ready configuration with dual-output ports and pressure-isolated distribution lines compliant with CGA G-4.1 standards.
Is the unit suitable for unattended overnight operation?
Yes. All safety interlocks remain active during idle periods; automatic water replenishment and thermal management ensure stable standby readiness for up to 72 hours without intervention.
How is calibration traceability maintained?
Factory calibration is performed using NIST-traceable flow and pressure standards; certificate of conformance includes uncertainty budgets per ISO/IEC 17025 guidelines.
Does the HG200 support third-party SCADA or LabVIEW integration?
Yes—Modbus RTU/TCP protocol support is available via firmware update; full register map and command syntax are provided in the technical integration manual.
