XiYou XYAH-5000G High-Purity Hydrogen & Air Integrated Gas Generator

Overview

The XiYou XYAH-5000G is an integrated high-purity hydrogen and compressed air generator engineered for continuous, reliable operation in analytical laboratories deploying gas chromatography (GC), gas chromatography–mass spectrometry (GC–MS), and other gas-dependent instrumentation. Unlike conventional cylinder-based supply systems, this generator employs membrane-separated alkaline electrolysis (KOH aqueous solution) to produce hydrogen on-demand, while incorporating a high-efficiency imported air compressor to deliver clean, oil-free, particle- and moisture-controlled compressed air. The system operates on the principle of water electrolysis under controlled current density and thermal management, yielding hydrogen gas with certified purity ≥99.999% (5.0 grade), meeting stringent requirements for detector fuel gas and carrier gas makeup in flame ionization detectors (FID), thermal conductivity detectors (TCD), and electron capture detectors (ECD). Its integrated architecture eliminates cross-contamination risks between hydrogen and air streams, ensuring independent pressure and flow regulation—critical for method reproducibility and instrument stability.

Key Features

• Integrated dual-gas architecture: Simultaneous generation of high-purity hydrogen and regulated compressed air within a single footprint (480 × 300 × 365 mm), reducing spatial demand by >60% versus separate generators.
• Triple-stage hydrogen purification: Palladium-doped molecular sieve, desiccant, and sub-micron particulate filtration ensure residual oxygen <0.1 ppm, moisture <1 ppmv, and total hydrocarbons <0.01 ppmv—validated per ISO 8573-1 Class 1:2:1.
• Dual-stage air pressure regulation with triple-stage filtration: Includes coalescing pre-filter, activated carbon adsorption, and ultra-low penetration air (ULPA) final filter, delivering oil-free air compliant with ISO 8573-1 Class 1:4:1 for GC detector support and pneumatic actuation.
• Tubular alkaline electrolyzer with automatic anti-backflow control: Patented electrode geometry and gravity-assisted electrolyte containment prevent caustic carryover into gas lines—eliminating risk of detector contamination or column degradation.
• Fail-safe engineering: Integrated over-pressure relief valves (set at 0.45 MPa for H₂, 0.55 MPa for air), real-time temperature monitoring, and automatic shutdown on electrolyte level deviation or current anomaly.
• Low-maintenance design: Electrolyte service interval ≥12 months under continuous operation; no consumable membranes or catalyst cartridges required.

Sample Compatibility & Compliance

The XYAH-5000G is validated for use with all major GC and GC–MS platforms requiring ultra-high-purity hydrogen (e.g., Agilent 8890/8860, Thermo Scientific TRACE 1300, Shimadzu GC-2030) and stable air supply for FID, NPD, and PID detectors. It conforms to key regulatory expectations for analytical gas supply infrastructure: output stability supports USP and EP 2.2.47 chromatographic method robustness criteria; pressure and flow repeatability (±0.5% FS over 24 h) aligns with ASTM D6299 precision requirements for calibration gas delivery; and its electronic log architecture—including timestamped operational events and parameter history—enables alignment with FDA 21 CFR Part 11 data integrity principles when paired with compliant LIMS or instrument control software.

Software & Data Management

While the XYAH-5000G operates via embedded microcontroller with tactile keypad and LED status interface (no PC dependency), it provides RS-232 serial output for integration into laboratory-wide monitoring systems. All operational parameters—including real-time H₂ flow (mL/min), outlet pressure (MPa), electrolyzer temperature (°C), and cumulative runtime (hours)—are logged internally with 30-day buffer retention. Exportable ASCII-formatted logs support audit-ready review for GLP/GMP inspections. Optional analog 4–20 mA outputs enable connection to building management systems (BMS) for centralized gas supply oversight.

Applications

• Fuel gas supply for flame-based GC detectors (FID, FPD, NPD), where consistent H₂ stoichiometry directly impacts sensitivity and linear dynamic range.
• Make-up gas for mass spectrometer ion sources requiring ultra-dry, hydrocarbon-free hydrogen.
• Carrier gas auxiliary in hydrogen-selective applications (e.g., methanizer setups, reductive pyrolysis).
• Compressed air source for detector air supply, autosampler purge, and pneumatic valve actuation—replacing noisy, maintenance-intensive standalone compressors.
• Research environments requiring long-term unattended operation (e.g., environmental monitoring labs, petrochemical QA/QC centers, pharmaceutical stability testing suites).

FAQ

Does the XYAH-5000G require deionized water or distilled water for electrolysis?
Yes—only ASTM Type II or higher purity water (resistivity ≥1 MΩ·cm) is permitted. Tap or softened water will cause rapid electrode fouling and void warranty.
Can the hydrogen and air outputs be used simultaneously at maximum rated flow?
Yes—the unit’s thermal management and power regulation are designed for concurrent full-load operation without derating or stability compromise.
Is remote monitoring or Ethernet connectivity available?
No native Ethernet port is included; however, RS-232 output allows integration with third-party SCADA or LabVantage via standard protocol converters.
What safety certifications does the unit hold?
It complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking per EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU.
How often must the electrolyte be replaced?
Under typical usage (8 h/day, 5 days/week), the KOH solution requires replenishment every 12–14 months—verified by built-in conductivity monitoring and visual inspection port.
