PEAK INFINITY XE 5021 Nitrogen Generator

Overview

The PEAK INFINITY XE 5021 Nitrogen Generator is a high-capacity, membrane-based on-site nitrogen supply system engineered for continuous, reliable operation in analytical laboratories requiring laboratory-grade nitrogen gas. Utilizing hollow-fiber polymeric membrane separation technology, the INFINITY XE 5021 selectively permeates oxygen, water vapor, carbon dioxide, and other trace gases from compressed air—retaining nitrogen with consistent purity up to 99.5% at flow rates spanning 20 to 260 L/min. Designed for integration into multi-instrument environments, it serves as a centralized nitrogen source for multiple LC-MS systems, GC carrier gas applications, sample preparation stations, and inert atmosphere enclosures. Its solid-state architecture—devoid of moving parts, compressors, or cryogenic components—ensures silent operation (<45 dB(A)), minimal thermal load, and long-term stability under continuous duty cycles. The system operates exclusively with clean, dry feed air meeting ISO 8573-1:2010 Class 1.4.1 specifications (i.e., ≤0.01 µm particulate filtration, ≤0.01 mg/m³ oil content, and dew point ≤−40 °C), ensuring optimal membrane lifetime and consistent gas quality.

Key Features

• Membrane-based nitrogen generation with no rotating components, eliminating mechanical wear and reducing failure risk
• Wide dynamic flow range (20–260 L/min) with pressure-regulated output up to 135 psi (9.3 bar), compatible with high-pressure LC-MS interfaces and pneumatic actuators
• Stable nitrogen purity of 95–99.5%, validated across full flow range using onboard electrochemical sensors and factory-calibrated trace oxygen analyzers
• Dew point performance consistently maintained at −40 °C or lower, supporting moisture-sensitive applications including ESI ion sources and solvent evaporation systems
• Universal power input (100–230 VAC, 50/60 Hz) with integrated surge protection and thermal cut-off safeguards
• Compact footprint (500 × 500 × 995 mm) optimized for floor-standing deployment in controlled laboratory environments with limited utility space

Sample Compatibility & Compliance

The INFINITY XE 5021 is not intended for direct ambient air intake; it requires externally supplied compressed air that complies with ISO 8573-1:2010 Class 1.4.1 for particulate, oil aerosol, and water content. This prerequisite ensures membrane integrity and avoids premature fouling or irreversible flux decline. When integrated with PEAK’s optional pre-filtration modules—including coalescing filters, desiccant dryers, and oil removal adsorbents—the system achieves full compliance with ISO 8573-1:2010 Class 1.1.1, enabling use in regulated environments governed by GLP, GMP, or ISO/IEC 17025 standards. While the generator itself does not require periodic calibration per ISO/IEC 17025 Clause 6.4, its output gas quality is verifiable via external trace oxygen and dew point analyzers compliant with ASTM D6667 and ISO 8573-3.

Software & Data Management

The INFINITY XE 5021 operates as a standalone hardware platform without embedded microprocessor control or digital communication ports (e.g., RS-232, Ethernet, or USB). All operational parameters—including inlet pressure, outlet pressure, flow rate, and real-time purity estimation—are monitored via analog gauges and LED indicators on the front panel. For laboratories implementing instrument connectivity frameworks (e.g., LabVantage, Thermo Fisher SampleManager, or Waters Empower), third-party analog-to-digital signal converters may be deployed to log pressure and flow data into LIMS or ELN systems. PEAK provides documented electrical interface schematics and 4–20 mA analog output options (available upon request) to support audit-ready data capture in FDA 21 CFR Part 11–compliant workflows where electronic records are required.

Applications

• Primary nitrogen source for two or more LC-MS systems operating simultaneously, eliminating dependency on high-pressure nitrogen cylinders or liquid nitrogen dewars
• Carrier gas for gas chromatography (GC) and GC-MS configurations requiring stable flow and low moisture/oxygen content
• Inert purge gas for autosampler trays, solvent reservoirs, and nitrogen blankets in reaction monitoring setups
• Collision gas in tandem mass spectrometry (MS/MS) instruments where consistent molecular weight discrimination depends on gas density and thermal conductivity uniformity
• Instrument purge and desolvation gas in ICP-MS and MALDI-TOF platforms sensitive to hydrocarbon contamination and humidity-induced signal drift

FAQ

Does the INFINITY XE 5021 include an integrated air compressor?

No. It is designed for use with externally supplied clean, dry compressed air meeting ISO 8573-1:2010 Class 1.4.1. Optional PEAK air compression and pre-filtration packages are available separately.
What maintenance intervals are recommended?

Annual inspection of inlet filter elements and verification of membrane housing integrity. No scheduled replacement of membranes is required under compliant feed air conditions; typical service life exceeds 15,000 operating hours.
Can output purity be adjusted in real time?

Purity is inversely related to flow rate and inlet pressure. While no user-adjustable purity setpoint exists, the system maintains ≥99.5% at flows ≤120 L/min and ≥95% across the full 20–260 L/min range when operated within specified inlet pressure bounds.
Is the unit suitable for ISO 13485-certified medical device manufacturing labs?

Yes—when paired with documented feed air validation, routine purity/dew point verification, and change control procedures aligned with QSR requirements, the INFINITY XE 5021 supports nitrogen supply in Class II/III device production environments.
What safety certifications does it carry?

CE-marked per EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU; compliant with RoHS 2011/65/EU and REACH Regulation (EC) No. 1907/2006.
