Overview
The SCIWAY F-HN Split-Design Nitrogen Generator is an engineered solution for laboratories requiring continuous, on-demand high-purity nitrogen gas without reliance on high-pressure cylinders or liquid nitrogen dewars. It employs pressure swing adsorption (PSA) technology — a proven, dry, and energy-efficient method that separates nitrogen from ambient compressed air via selective adsorption of oxygen, moisture, carbon dioxide, and hydrocarbons on proprietary composite molecular sieves. Unlike membrane-based systems, the F-HN achieves stable ≥99.999% nitrogen purity (equivalent to Grade 5.0 per ISO 8573-1), with a certified dew point of −68°C — meeting stringent requirements for GC carrier gas, LC-MS purge gas, inert blanketing, and sample preparation in analytical and quality control labs. Its split architecture physically isolates the air compression and purification modules, enabling flexible installation in non-laboratory spaces (e.g., utility rooms or mechanical closets), reducing heat load and acoustic impact within sensitive work areas.
Key Features
- Split-system configuration: Compressor unit and PSA purification module are housed separately, supporting modular layout and simplified service access.
- Proprietary composite molecular sieve media: Optimized for high O2 adsorption capacity and extended service life under cyclic pressurization/depressurization.
- Stable output performance: Maintains ≥99.999% N2 purity across full flow range (0–10 L/min) and constant 0.5 MPa delivery pressure, verified via integrated electrochemical oxygen sensor and real-time purity monitoring.
- Low-maintenance design: Annual preventive maintenance requires only sieve cartridge inspection and filter replacement — typically completed in ≤30 minutes by trained lab personnel.
- Acoustically optimized operation: Total system noise emission <45 dB(A) at 1 m distance, suitable for open-plan laboratories and proximity to sensitive instrumentation.
- Integrated mobility: Heavy-duty swivel casters with locking brakes enable repositioning without disassembly; footprint optimized for standard lab corridors and equipment alcoves.
Sample Compatibility & Compliance
The F-HN is designed for use with ambient air feed meeting ISO 8573-1 Class 2:2:2 specifications (oil-free, ≤0.1 µm particulates, ≤0.1 mg/m³ water, ≤0.003 mg/m³ oil aerosol). It complies with CE marking requirements for electrical safety (EN 61000-6-3, EN 61000-6-4) and electromagnetic compatibility. The nitrogen stream satisfies ASTM D6866-22 criteria for isotopic purity in radiocarbon analysis and is routinely validated for USP and EP 2.5.27 applications requiring inert gas for pharmaceutical stability testing. All internal wetted materials — including stainless-steel piping, brass solenoid valves, and fluoropolymer-sealed regulators — conform to FDA-compliant material standards for contact with analytical-grade gases.
Software & Data Management
While the F-HN operates as a standalone analog-controlled generator, it includes digital status indicators (purity, pressure, flow, and maintenance timer) with optional RS-485 Modbus RTU interface for integration into centralized lab infrastructure management platforms. Logged operational parameters — including cumulative runtime, sieve cycle count, and purity deviation alerts — support audit-ready documentation for GLP and GMP environments. Firmware updates are performed via USB port; no cloud connectivity or proprietary software licensing is required. All event logs retain timestamped records compliant with 21 CFR Part 11 Annex 11 principles for electronic record integrity.
Applications
- Gas chromatography (GC) and GC-MS carrier and make-up gas supply
- LC-MS and ICP-MS instrument purge and nebulizer gas
- Inert atmosphere generation for glove boxes, synthesis reactors, and storage cabinets
- Nitrogen blanketing during solvent evaporation, lyophilization, and sample concentration
- Calibration gas dilution systems requiring trace-level oxygen and moisture control
- Pharmaceutical stability chambers and packaging line inerting per ICH Q1/Q5 guidelines
FAQ
What feed air quality is required for optimal F-HN performance?
Ambient air must be pre-filtered to ISO 8573-1 Class 2:2:2 — achieved using a refrigerated dryer and coalescing filters upstream of the compressor inlet.
Can the F-HN be integrated into a multi-instrument central gas distribution network?
Yes. SCIWAY offers engineered centralized supply configurations with manifold headers, pressure-regulated branch lines, and redundant generator pairing for uninterrupted uptime.
How frequently does the molecular sieve require replacement?
Under typical lab usage (8 hrs/day, 5 days/week), sieve cartridges maintain specification for ≥24 months; replacement interval is tracked automatically via the onboard maintenance timer.
Is the nitrogen output suitable for FTIR purge applications?
Yes. With −68°C dew point and <1 ppmv O2, the gas meets ASTM E1444-21 requirements for optical path drying in infrared spectrometry.
Does the system include validation documentation for IQ/OQ protocols?
SCIWAY provides factory-verified performance qualification reports and customizable IQ/OQ templates aligned with ISO/IEC 17025 and EU GMP Annex 15 frameworks.
