Overview
The XiYou XYN-300 Membrane-Based Nitrogen Generator is an engineered solution for laboratories requiring a continuous, on-demand supply of high-purity nitrogen gas with minimal infrastructure dependency. Unlike pressure swing adsorption (PSA) or electrochemical systems, the XYN-300 employs a selective polymer membrane separation process—where compressed air feedstock passes through hollow-fiber membranes that preferentially permeate oxygen, water vapor, and other trace gases, while retaining nitrogen in the non-permeate stream. This principle delivers stable, oil-free nitrogen without consumables, moving parts, or routine maintenance beyond periodic filter replacement. Designed for integration into analytical instrumentation—including GC carrier gas supply, LC-MS purge lines, glovebox inerting, and sample preparation environments—the XYN-300 operates silently and reliably under ambient laboratory conditions, supporting method consistency and regulatory compliance in QA/QC and research settings.
Key Features
- Stable membrane-based nitrogen generation with no catalysts, electrolytes, or desiccants required
- Integrated dual-stage particulate and coalescing filtration upstream of the membrane module to protect membrane integrity and ensure long service life
- Factory-calibrated pressure regulation system with default output set at 0.4 MPa; adjustable up to 0.5 MPa for compatibility with diverse instrument inlet specifications
- Automatic shutdown circuitry activated upon power loss, preventing uncontrolled gas release and ensuring safe operation during unexpected outages
- Compact footprint (W × D × H ≈ 260 × 320 × 420 mm) and low mass (<12 kg), enabling benchtop deployment without dedicated utility connections
- Efficient switch-mode power supply delivering consistent electrical input across line voltage fluctuations (100–240 V AC, 50/60 Hz), minimizing energy waste and thermal load
Sample Compatibility & Compliance
The XYN-300 is compatible with ambient air as its sole feed gas source and requires no external drying or compression equipment when used with standard lab-grade oil-free compressors (recommended inlet pressure: 0.7–1.0 MPa). Its nitrogen output meets critical purity thresholds for sensitive applications: residual oxygen content remains below 3 ppm (v/v), and dew point is consistently maintained below −70 °C—equivalent to ISO 8573-1 Class 2.2.1 for compressed gases. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 as a standalone device, the generator supports GLP- and GMP-aligned workflows when deployed with validated instruments and documented operational procedures. It complies with IEC 61010-1 safety standards for laboratory electrical equipment and incorporates CE-marked internal components.
Software & Data Management
The XYN-300 operates as a stand-alone hardware unit with no embedded microprocessor, firmware, or digital interface. All control logic is implemented via analog circuitry and mechanical regulators—eliminating software dependencies, cybersecurity risks, or validation overhead associated with digital controllers. This architecture ensures deterministic behavior, full auditability of operational states (e.g., pressure, flow, power status), and seamless integration into legacy or regulated environments where software qualification would otherwise be required. Users maintain complete control over calibration records, preventive maintenance logs, and gas quality verification (e.g., via external O₂ analyzers or dew point meters) using their existing LIMS or paper-based documentation systems.
Applications
- Carrier gas supply for capillary gas chromatography (GC), particularly for FID, TCD, and ECD detectors requiring stable, ultra-dry nitrogen
- Purge and trap systems, headspace analysis, and automated sample introduction modules
- Inert atmosphere maintenance in nitrogen cabinets, desiccators, and anaerobic workstations
- Blanketing and purging during solvent evaporation, lyophilization, and reactive synthesis steps
- Support gas for elemental analyzers (e.g., CHNS/O), FTIR purge lines, and plasma cleaning systems
FAQ
What feed gas is required for the XYN-300?
Compressed, oil-free, and particle-filtered ambient air at 0.7–1.0 MPa is required. An external compressor and pre-filtration system must be provided by the user.
Does the XYN-300 require regular consumables or replacement parts?
Only the inlet particulate and coalescing filters require periodic replacement—typically every 6–12 months depending on air quality. The membrane module has a rated service life exceeding 15,000 operating hours under specified conditions.
Can output pressure be adjusted beyond the factory setting?
Yes—the pressure regulator is manually adjustable within the 0–0.5 MPa range. However, sustained operation above 0.4 MPa may reduce flow stability and accelerate membrane aging.
Is the nitrogen output suitable for use with mass spectrometry?
While the O₂ < 3 ppm and dew point < −70 °C specifications meet baseline requirements for many LC-MS and GC-MS applications, users should verify compatibility with their specific instrument manufacturer’s gas specifications and conduct periodic purity verification.
How is performance verified during routine operation?
Users are advised to implement periodic verification using calibrated trace oxygen analyzers and chilled-mirror or capacitance-based dew point meters—procedures aligned with ASTM D6667 and ISO 8573-3 standards.
