Parker UHPN2-1100UK & HPN2-2000UK Ultra-High-Purity Nitrogen Generators

Overview

The Parker UHPN2-1100UK and HPN2-2000UK ultra-high-purity nitrogen generators are engineered for continuous, on-demand production of laboratory-grade nitrogen from clean, oil-free compressed air. Utilizing pressure swing adsorption (PSA) technology with dual-bed molecular sieve architecture, these systems separate atmospheric nitrogen from oxygen, moisture, and trace contaminants—delivering stable, consistent gas output without reliance on high-pressure cylinders. The UHPN2-1100UK achieves 99.9999% purity (≤0.1 ppm O₂, ≤0.1 ppm H₂O), meeting stringent requirements for electron-capture detectors (ECD), high-resolution mass spectrometry (HRMS), and ultra-trace elemental analysis. The HPN2-2000UK provides 99.99% purity (≤10 ppm O₂, ≤10 ppm H₂O), optimized for routine GC-FID, LC-MS mobile phase sparging, and inert purge applications. Both models integrate real-time pressure regulation, automatic dew point monitoring, and fail-safe shutdown logic—ensuring operational continuity and analytical integrity across 24/7 laboratory environments.

Key Features

• PSA-based dual-bed nitrogen separation with automated valve sequencing for uninterrupted output and extended sieve life
• Integrated air preparation module: coalescing filter (0.01 µm), activated carbon stage, and desiccant dryer (−40 °C dew point)
• Digital front-panel interface with LCD display showing real-time flow rate, outlet pressure (0–10 bar adjustable), purity status, and maintenance alerts
• Low-noise operation (<55 dBA at 1 m) and energy-efficient design (≤350 W typical power draw)
• Modular construction enabling field-serviceable components—no proprietary tools required for filter or sieve replacement
• Optional analog (0–10 V) and digital (RS-485 Modbus RTU) outputs for integration into lab-wide gas monitoring systems

Sample Compatibility & Compliance

These generators supply nitrogen compatible with a broad spectrum of analytical instrumentation requiring certified carrier, purge, or shielding gases—including Agilent, Thermo Fisher, Waters, PerkinElmer, and Shimadzu platforms. Output meets ASTM D6866-22 (for carbon-14–free nitrogen in radiocarbon dating prep), ISO 8573-1 Class 1:2:1 (compressed air quality for instrument air), and USP specifications for residual oxygen and moisture in pharmaceutical process gases. All units are designed and tested per IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions), and conform to UKCA and CE marking directives for laboratory equipment placed on the GB and EU markets. Full traceability documentation—including factory calibration certificates, material declarations (RoHS/REACH), and risk assessment reports—is provided with each unit.

Software & Data Management

While the UHPN2-1100UK and HPN2-2000UK operate as standalone hardware, optional Parker SmartLink™ firmware enables remote diagnostics via Ethernet or Wi-Fi. Logged parameters—including cumulative runtime, sieve cycle count, inlet pressure deviation, and alarm history—are exportable as CSV files for GLP/GMP audit trails. The system supports time-stamped event logging compliant with FDA 21 CFR Part 11 requirements when deployed with validated network authentication and electronic signature protocols. No proprietary software installation is required; configuration and monitoring are accessible through any modern web browser using HTTPS-secured connections.

Applications

• Carrier gas for gas chromatography (GC), including ECD, TCD, and FID detectors requiring sub-ppm oxygen stability
• Collision/reaction gas and source purge in inductively coupled plasma mass spectrometry (ICP-MS) and triple-quadrupole LC-MS/MS
• Inert atmosphere generation for thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), and thermomechanical analysis (TMA)
• Mobile phase degassing and solvent delivery blanking in ultra-high-performance liquid chromatography (UHPLC)
• Blanketing and purging during sample preparation workflows involving hygroscopic or oxidation-sensitive standards (e.g., organometallics, reference materials for EPA Method 8270)

FAQ

What compressed air quality is required for optimal performance?
Oil-free, particle-free air with ≤0.1 ppm hydrocarbons and a dew point ≤−40 °C is recommended. Parker’s integrated air prep module accommodates inlet air up to ISO 8573-1 Class 2:2:2.
Can these generators support multiple instruments simultaneously?
Yes—when configured with a manifold distribution system and appropriately sized stainless-steel tubing (1/4″ OD minimum), both models can serve up to three GCs or two LC-MS systems with pressure-regulated branch lines.
How often do consumables require replacement?
Coalescing filters: every 6 months under continuous use; desiccant and carbon stages: annually; molecular sieves: 3–5 years depending on inlet air quality and duty cycle.
Is validation support available for regulated laboratories?
Parker provides IQ/OQ protocol templates, commissioning checklists, and third-party validation assistance through authorized service partners—fully aligned with ISO/IEC 17025 and GAMP 5 guidelines.
Do these units meet local electrical safety standards for deployment in the UK and EU?
Yes—both models carry UKCA and CE markings, comply with the Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, and include full technical construction files available upon request.
