Infinity XE 5011-5041 Single nitrogen source for multiple applications

Importance of the Topic

The availability of reliable, high-purity nitrogen is essential for a wide range of analytical techniques in modern laboratories. Consistent gas quality directly affects the sensitivity, accuracy, and reproducibility of instruments such as LC-MS, NMR, ELSD, FT/MS, and glovebox operations. Decentralized gas generation systems can lower operational costs and improve workflow efficiency by eliminating dependence on external gas cylinders.

Objectives and Overview of the Article

This application note introduces the Infinity XE 5011–5041 series nitrogen generators from Peak Scientific. It outlines the design goals—delivering 10–520 L/min of nitrogen at adjustable purities (95–99.5%) and up to 135 psi output pressure—while ensuring low maintenance and integrated safety features. The document also highlights typical laboratory applications and the generator’s compatibility with ISO 8573-1:2010 Class 1.4.1 compressed air sources.

Methodology and Instrumentation

The Infinity XE series employs advanced membrane separation technology to extract nitrogen from compressed air. A built-in purity fail-safe continuously monitors output quality, triggering warnings or automatic shutdown if purity falls below set thresholds. The compact skid-mounted unit requires an external compressor meeting ISO 8573-1:2010 Class 1.4.1 standards. Key instrument characteristics are:

• Flow range: 10–520 L/min across four models (5011–5041)
• Purity adjustable between 95% and 99.5%
• Maximum outlet pressure: 135 psi
• Electrical input: 100–230 VAC, 50/60 Hz, 40 W consumption
• Operating temperature: 5–30 °C
• Dimensions: 500 × 500 × 995 mm; weight 75–90 kg

Main Results and Discussion

Performance testing confirms that each model meets its specified flow and purity targets under varying inlet pressures (60–145 psi) and air quality conditions. The purity safeguard system reliably detects shifts in membrane efficiency, safeguarding downstream instruments. Minimal moving parts translate to reduced noise and lower service frequency.

Benefits and Practical Applications

The Infinity XE series offers laboratories:

• Continuous on-site nitrogen supply, reducing cylinder handling and delivery costs
• Flexible purity settings to match diverse analytical requirements
• Compact footprint for space-constrained facilities
• Automated safety features to protect sensitive detectors
• Low maintenance through membrane technology, backed by a 12-month warranty and optional service plans

Future Trends and Potential Applications

Advancements in membrane materials and smart monitoring will drive even higher purities at lower energy input. Integration with laboratory information management systems (LIMS) and predictive maintenance algorithms can further optimize uptime. Expanding applications may include semiconductor, pharmaceutical process analytics, and on-site gas supply for field research.

Conclusion

The Peak Scientific Infinity XE 5011–5041 series provides a robust, flexible solution for laboratory nitrogen needs. By combining membrane separation with integrated safety features and low maintenance requirements, these generators deliver consistent performance across a broad range of analytical workflows.
