Peak INFINITY XE 5020 Nitrogen Generator

Overview

The PEAK INFINITY XE 5020 is a high-reliability, membrane-based nitrogen generator engineered for continuous, on-demand supply of laboratory-grade nitrogen gas to support demanding analytical applications—particularly liquid chromatography–mass spectrometry (LC-MS) systems. Unlike cryogenic or pressure swing adsorption (PSA) systems, the INFINITY XE 5020 employs hollow-fiber polymeric membrane technology to separate nitrogen from compressed air feed gas, delivering consistent purity without consumables, moving parts, or periodic regeneration cycles. Its design targets laboratories with access to clean, dry instrument air meeting ISO 8573-1:2010 Class 1.4.1 specifications (i.e., ≤0.1 µm particulate filtration, ≤0.01 mg/m³ oil content, and dew point ≤−40 °C at operating pressure). The unit operates silently and requires no scheduled maintenance beyond routine inlet filter inspection—making it ideal for integration into controlled environments such as core analytical labs, QC facilities, and GLP-compliant research settings.

Key Features

• Membrane separation architecture with zero moving parts—ensuring silent, vibration-free operation and eliminating mechanical wear
• Stable output flow range of 20–120 L/min at 100 psi, scalable to serve multiple LC-MS instruments simultaneously
• Consistent nitrogen purity up to 99.5% (v/v), validated across full flow range and ambient temperature fluctuations
• Dew point performance of −40 °C at outlet pressure, compatible with electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) source requirements
• Compact footprint (500 × 500 × 995 mm) optimized for under-bench or adjacent-lab installation
• Wide-input voltage compatibility (100–230 VAC, 50/60 Hz) enabling global deployment without external transformers
• Integrated safety monitoring including overpressure relief, thermal cutoff, and real-time pressure diagnostics

Sample Compatibility & Compliance

The INFINITY XE 5020 is not intended for standalone air compression; it requires a certified external air source compliant with ISO 8573-1:2010 Class 1.4.1. When paired with appropriate upstream filtration (e.g., coalescing, activated carbon, and desiccant stages), the system meets the gas quality prerequisites defined in ASTM D6349 for LC-MS carrier and nebulizer gases. While the generator itself does not carry CE marking for medical device use, its construction adheres to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards. For regulated environments, the absence of consumables and fixed-purity output supports audit readiness under FDA 21 CFR Part 11 when integrated with validated data acquisition workflows.

Software & Data Management

The INFINITY XE 5020 operates as a stand-alone hardware platform with analog pressure and flow monitoring—no embedded firmware, touchscreen interface, or network connectivity is included. This design minimizes cybersecurity surface area and eliminates software validation overhead for GxP-regulated labs. Operational status is indicated via LED panel (power, pressure, fault), and all critical parameters—including inlet pressure, outlet pressure, and flow stability—are accessible via calibrated analog gauges. For laboratories requiring digital logging, third-party pressure transducers and PLC-compatible 4–20 mA outputs can be integrated into existing building management or LIMS infrastructure without modifying the generator’s core architecture.

Applications

• Primary nitrogen supply for multi-instrument LC-MS laboratories, including QTOF, triple quadrupole, and ion trap platforms
• Nebulizer, drying, and curtain gas delivery in ESI and APCI sources
• Blank solvent purge and mobile phase sparging in UHPLC systems
• Carrier gas for headspace GC and purge-and-trap sample introduction modules
• Instrument purging and enclosure inerting in sensitive elemental analysis suites (e.g., ICP-MS sample introduction zones)
• Backup or primary nitrogen source in facilities where liquid nitrogen logistics are cost-prohibitive or safety-constrained

FAQ

Does the INFINITY XE 5020 include an integrated air compressor?
No. It is a nitrogen generator only and requires an external, clean, dry compressed air supply meeting ISO 8573-1:2010 Class 1.4.1.
Can it support more than one LC-MS system simultaneously?
Yes—its 20–120 L/min adjustable output enables concurrent supply to up to three standard LC-MS instruments operating typical ESI source flows (3–15 L/min each).
What maintenance is required?
None beyond periodic inspection and replacement of the inlet coalescing filter (recommended every 6–12 months depending on air quality). No membranes require replacement under normal operating conditions.
Is the nitrogen purity affected by ambient temperature or altitude?
Purity remains stable within ±0.2% across ambient temperatures of 10–35 °C and elevations up to 2,000 m ASL, provided inlet air dew point and pressure remain within specification.
How is compliance with regulatory gas quality standards demonstrated?
PEAK provides factory-issued Certificate of Conformance documenting dew point, purity, and pressure performance at rated flow. Users may perform in-house verification using ISO 8573-3 compliant moisture analyzers and ASTM D6349-compliant gas purity analyzers.
