Peak INFINITY XE 5031 Nitrogen Generator

Overview

The PEAK INFINITY XE 5031 Nitrogen Generator is an engineered solution for laboratories requiring continuous, on-demand nitrogen supply at high purity and stable flow rates—specifically optimized for supporting multiple high-performance liquid chromatography–mass spectrometry (LC-MS) systems simultaneously. Utilizing proprietary hollow-fiber membrane separation technology, the INFINITY XE 5031 selectively permeates oxygen, carbon dioxide, water vapor, and other trace gases from a clean, dry compressed air feed, retaining nitrogen with consistent purity up to 99.5% (v/v). Unlike pressure swing adsorption (PSA) systems, this membrane-based architecture contains no moving parts, eliminating mechanical wear, vibration, and audible operational noise—making it suitable for installation in shared lab spaces, cleanrooms, or near sensitive instrumentation.

Key Features

• Continuous nitrogen output across a scalable flow range of 30–390 L/min—enabling centralized gas supply for up to four LC-MS instruments or equivalent analytical platforms.
• Stable delivery pressure up to 135 psi (9.3 bar), compatible with electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and other high-pressure LC-MS interface requirements.
• Consistent nitrogen purity of ≥99.5% (v/v) with a certified dew point of −40 °C, meeting stringent moisture and hydrocarbon specifications for mass spectrometry and GC carrier applications.
• Zero-maintenance core design: no valves, compressors, or desiccant beds; only periodic inspection of inlet filtration and membrane integrity per ISO 8573-1:2010 Class 1.4.1 air quality compliance.
• Compact footprint (500 × 500 × 995 mm) with universal input power (100–230 VAC, 50/60 Hz), facilitating integration into existing utility infrastructure without dedicated electrical or ventilation upgrades.

Sample Compatibility & Compliance

The INFINITY XE 5031 is designed for use with externally supplied compressed air meeting ISO 8573-1:2010 Class 1.4.1 specifications—i.e., ≤0.1 µm particle size, ≤0.01 mg/m³ total oil content, and dew point ≤−40 °C at operating pressure. While the generator itself does not include an integrated compressor, PEAK offers optional pre-engineered air preparation packages—including refrigerated dryers, coalescing filters, and oil-free scroll compressors—to ensure full system compliance. The unit conforms to IEC 61010-1:2010 safety standards for laboratory equipment and supports GLP/GMP environments through documented validation protocols, including IQ/OQ documentation templates and traceable calibration records for flow, pressure, and purity verification.

Software & Data Management

The INFINITY XE 5031 operates as a standalone hardware platform with embedded digital monitoring—featuring real-time LED display of outlet pressure, flow rate, and system status indicators. Though it lacks onboard data logging or Ethernet connectivity, its analog 4–20 mA outputs and dry-contact alarm relays enable seamless integration into centralized lab infrastructure management systems (LIMS) or building automation platforms. All operational parameters remain accessible via front-panel interface, supporting manual audit trails aligned with FDA 21 CFR Part 11 principles when paired with external electronic loggers. PEAK provides comprehensive validation support documentation—including risk assessments, URS alignment, and FAT/SAT reports—for regulated pharmaceutical, clinical, and contract research organizations.

Applications

• LC-MS nitrogen supply for ESI and APCI sources across pharmaceutical QC, metabolomics, and proteomics workflows.
• Carrier and purge gas for gas chromatography (GC) and headspace analysis where ultra-dry, high-purity nitrogen minimizes baseline drift and column degradation.
• Inert blanketing during sample preparation, solvent evaporation, and reagent storage in analytical chemistry labs.
• Backup or primary nitrogen source for elemental analyzers (e.g., CHNS/O), FTIR purge lines, and glovebox purging in materials science facilities.
• Replacement for high-pressure nitrogen cylinders in multi-user core facilities—reducing logistical overhead, safety hazards, and recurring supply chain dependencies.

FAQ

Does the INFINITY XE 5031 require an external air supply?
Yes—it is designed exclusively for use with clean, dry compressed air meeting ISO 8573-1:2010 Class 1.4.1 specifications. Integrated air compression is not included but can be supplied as part of a complete PEAK Infinity Gas Solution.
What maintenance intervals are recommended?
No scheduled maintenance is required for the membrane module under normal operating conditions. Inlet particulate and coalescing filters should be inspected every 6–12 months depending on ambient air quality; replacement frequency is determined by differential pressure monitoring.
Can the system be validated for GxP environments?
Yes—PEAK provides IQ/OQ protocol templates, calibration certificates traceable to NIST standards, and validation support services compliant with ASTM D6349, USP , and ISO/IEC 17025 requirements.
Is the nitrogen purity affected by fluctuating inlet air pressure?
The membrane separation process maintains consistent purity across the specified inlet pressure range (60–145 psi); however, sustained operation below 60 psi may reduce flow stability and compromise long-term membrane performance.
What safety certifications does the unit hold?
The INFINITY XE 5031 complies with IEC 61010-1:2010 for electrical safety and carries CE marking for EMC and low-voltage directives. It is not classified as pressure equipment under PED 2014/68/EU due to its non-pressurized membrane housing design.
