PEAK INFINITY XE 5011 Nitrogen Generator

Overview

The PEAK INFINITY XE 5011 Nitrogen Generator is an engineered membrane-based gas generation system designed for continuous, on-demand production of high-purity nitrogen in analytical laboratory environments. It operates on the principle of selective permeation through hollow-fiber polymeric membranes, where compressed air—supplied externally—is separated into enriched nitrogen (retentate stream) and oxygen-enriched exhaust (permeate stream). This physical separation process requires no consumables, chemical regeneration, or cryogenic cooling, delivering stable, dry nitrogen with consistent purity across its full 10–130 L/min flow range. The system is explicitly intended for integration into laboratories already equipped with clean, dry compressed air meeting ISO 8573-1:2010 Class 1.4.1 specifications (i.e., ≤0.1 µm particles, ≤0.01 mg/m³ oil content, and dew point ≤ –40 °C at operating pressure). Its solid-state architecture—devoid of compressors, valves, or rotating components—ensures silent operation (<45 dB(A)), zero vibration transmission, and minimal scheduled maintenance, making it suitable for placement inside instrument rooms, LC-MS suites, or near sensitive detection systems.

Key Features

• Membrane-based nitrogen generation with no moving parts—eliminates mechanical wear, lubrication requirements, and service downtime
• Continuous output flow adjustable from 10 to 130 L/min at up to 135 psi, supporting concurrent operation of multiple LC-MS, GC, and sample preparation instruments
• Consistent nitrogen purity of 95–99.5% (v/v), verified via built-in electrochemical sensor monitoring and factory-calibrated traceability
• Dew point stability at –40 °C (ISO 8573-1 Class 3), ensuring compatibility with moisture-sensitive applications including electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI)
• Wide input pressure tolerance (60–145 psi) accommodates variable upstream air supply conditions without performance degradation
• Universal power input (100–230 VAC, 50/60 Hz) with integrated surge suppression and thermal overload protection
• Compact footprint (500 × 500 × 995 mm) optimized for floor-standing deployment adjacent to instrumentation racks or within modular lab infrastructure

Sample Compatibility & Compliance

The INFINITY XE 5011 does not generate nitrogen from ambient air; it requires a pre-conditioned inlet air stream compliant with ISO 8573-1:2010 Class 1.4.1. Laboratories lacking such infrastructure may integrate optional PEAK-certified external air compressors and multi-stage pre-filtration systems—including coalescing, activated carbon, and desiccant drying stages—to meet this specification. The generator itself conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking under the EU Machinery Directive. While not intrinsically rated for hazardous locations, its non-sparking design and absence of ignition sources permit safe use in standard analytical labs operating under GLP and ISO/IEC 17025 frameworks. Output gas quality supports method compliance for USP , EP 2.5.27, and ASTM D6866-22 when paired with validated air supply and routine purity verification.

Software & Data Management

The INFINITY XE 5011 operates as a standalone hardware system with analog and digital status indicators (LEDs for power, flow, pressure, and purity alert), but includes no embedded microprocessor, touchscreen interface, or network connectivity. All operational parameters are monitored via calibrated front-panel gauges and fail-safe pressure relief mechanisms. For laboratories requiring audit-ready records, PEAK recommends integration with third-party building management systems (BMS) or lab information management systems (LIMS) via 4–20 mA analog outputs (optional accessory) for real-time logging of outlet pressure and flow rate. No firmware updates or software licensing are required, eliminating cybersecurity exposure and validation overhead associated with connected devices—aligning with FDA 21 CFR Part 11 expectations for “simple” utility equipment where electronic records are not primary.

Applications

• LC-MS nitrogen supply for nebulizing, drying, and curtain gases across single- and triple-quadrupole platforms (e.g., Thermo Scientific TSQ series, Waters Xevo TQ-S)
• GC carrier and detector gases (FID, NPD, ECD) where ultra-dry, hydrocarbon-free nitrogen is critical for baseline stability
• Sample evaporation systems (e.g., TurboVap®, Genevac) requiring inert, low-particulate gas streams
• Blanketing and purging in pharmaceutical stability chambers, glove boxes, and solvent handling stations
• Supporting automated sample introduction modules (e.g., CTC PAL, GERSTEL MPS) with synchronized gas demand profiles

FAQ

Does the INFINITY XE 5011 include an integrated air compressor?
No. It is a membrane-based nitrogen generator requiring an external, ISO 8573-1 Class 1.4.1-compliant compressed air source.
Can output purity be adjusted or tuned for specific applications?
Purity is inherently flow-dependent within the specified range (99.5% at minimum flow; ~95% at maximum flow); no user-adjustable purity setpoint exists—design prioritizes reproducibility over tunability.
What maintenance intervals are recommended?
Annual inspection of inlet filter elements and verification of membrane integrity via pressure drop measurement; no scheduled replacement of membranes unless performance drift exceeds ±2% purity or >5 psi differential pressure deviation.
Is the system compatible with 24/7 unattended operation?
Yes. Rated for continuous duty cycle with thermal shutdown protection and pressure-relief redundancy per EN ISO 4414.
Does PEAK provide IQ/OQ documentation packages?
Yes—validated installation and operational qualification protocols are available upon request, aligned with ASTM E2500-22 and GAMP 5 guidance for laboratory utility equipment.
