Overview
The PEAK Infinity Series Membrane-Based Nitrogen Generator is an engineered solution for continuous, on-demand nitrogen supply in analytical and preparative laboratory environments. Utilizing proprietary hollow-fiber membrane separation technology, the system selectively permeates oxygen, water vapor, and other trace gases from compressed air, delivering a stable stream of high-purity nitrogen (99.5% N₂) without consumables, catalysts, or pressure-swing adsorption (PSA) beds. Designed for integration with sensitive instrumentation—including LC-MS, GC, GC-MS, FTIR, TOC analyzers, and nitrogen blow-down evaporators—the Infinity platform eliminates reliance on high-pressure cylinders while maintaining strict gas quality consistency required for method reproducibility and regulatory compliance.
Key Features
- Modular scalability: Multiple models (Infinity NM, 50, and 90 series) support output capacities from 18 L/min to 1120 L/min N₂, enabling single-unit support for up to 16 LC-MS systems or 8 high-flow nitrogen evaporators.
- Low-maintenance architecture: Few moving parts; no desiccant replacement, carbon molecular sieve regeneration, or oil-lubricated compressors—reducing scheduled downtime and total cost of ownership.
- Integrated air preparation: Built-in refrigerated dryer, coalescing and particulate filtration, and activated carbon polishing ensure inlet air meets ISO 8573-1 Class 2:2:2 requirements prior to membrane separation.
- Acoustically optimized operation: Noise emission <55 dB(A) at 1 m distance, suitable for placement within analytical labs or shared instrument rooms without acoustic shielding.
- Mobile deployment-ready: Equipped with industrial-grade casters and leveling feet for flexible positioning; requires only standard electrical outlet and ambient air intake.
- Energy-efficient design: Optimized compressor duty cycle and membrane module thermal management reduce power consumption by up to 30% compared to equivalent PSA-based systems under comparable load profiles.
Sample Compatibility & Compliance
The Infinity Series is validated for use with major OEM analytical platforms, including AB Sciex TripleTOF®, Waters Xevo®, Thermo Scientific Q Exactive™, Agilent 6495C, and Shimadzu LCMS-8060. All units comply with IEC 61010-1 for laboratory equipment safety and are designed to meet the gas quality specifications outlined in ASTM D6349 (for LC-MS carrier gas), USP (for residual solvent analysis), and ISO 8573-1:2010 Class 2 for particulate, moisture, and oil content. Optional data logging modules support 21 CFR Part 11-compliant audit trails when integrated with PEAK’s iQ Software Suite.
Software & Data Management
PEAK iQ Software provides real-time monitoring of critical operational parameters—including inlet pressure, dew point, membrane stack temperature, nitrogen purity (via optional inline O₂ sensor), and cumulative runtime. The software supports configurable alarms, remote diagnostics via secure HTTPS interface, and export of CSV-formatted logs for GLP/GMP documentation. Firmware updates are delivered over-the-air with version-controlled rollback capability. For centralized lab infrastructure, iQ Server enables multi-generator fleet management, predictive maintenance scheduling, and integration with enterprise CMMS platforms via RESTful API.
Applications
- LC-MS mobile phase nebulization and collision gas supply across pharmaceutical QC, clinical toxicology, and environmental residue testing workflows.
- GC carrier gas for capillary column analysis requiring consistent flow and purity to minimize baseline drift and retention time variability.
- Nitrogen blow-down evaporation in sample prep labs handling volatile organic compounds (VOCs), pesticides, or metabolites—enabling precise temperature and flow control per channel.
- FTIR purge gas for optical path stabilization in hyphenated systems such as TGA-FTIR or GC-FTIR.
- TOC analyzer oxidant gas supply where low hydrocarbon and CO₂ content is essential to avoid background interference.
- Controlled-atmosphere glove boxes and inert storage cabinets requiring continuous low-oxygen environments.
FAQ
What is the expected service life of the membrane module?
Under normal operating conditions (inlet air meeting ISO 8573-1 Class 2:2:2), the hollow-fiber membrane stack is rated for ≥10,000 hours of continuous operation and is covered under PEAK’s 3-year extended warranty.
Can the Infinity generator be integrated into an existing lab air network?
Yes—models equipped with the optional AirLink™ interface can accept regulated plant air (6–8 bar, ≤3°C dew point) as input, eliminating the need for an integrated compressor.
Does the system require external cooling water or exhaust venting?
No. All Infinity models are air-cooled and operate as closed-loop systems; no external water connections or dedicated exhaust ducting are required.
How is nitrogen purity verified during operation?
While the membrane process delivers consistent 99.5% purity under specified inlet conditions, optional electrochemical O₂ sensors (0–1000 ppm range, ±2% accuracy) provide continuous inline verification with alarm thresholds configurable in iQ Software.
Is remote monitoring supported for GxP-regulated environments?
Yes—iQ Software includes electronic signature capability, user role-based access control, and immutable audit logs compliant with FDA 21 CFR Part 11 and EU Annex 11 requirements.
