Nitrogen Generator - Infinity 90 Series

Importance of the Topic

Reliable nitrogen supply is critical for many analytical workflows, especially sample evaporation and concentration processes.
On‐site generation reduces safety risks, recurring cylinder costs and environmental impact compared to bottled or bulk gas delivery.

Study Objectives and Overview

This document introduces the Infinity 90 Series perpetual‐flow nitrogen generators by Peak Scientific.
It aims to present performance characteristics, operational advantages and suitability for laboratory applications such as turbovap and evaporator systems.

Methodology and Instrumentation

The Infinity 90 Series uses pressure swing adsorption technology coupled with integrated filtration to produce high‐purity nitrogen continuously.
Key design elements include minimal moving parts for reduced maintenance and silent operation.
The generators connect directly to an existing compressed air supply and feature caster wheels for mobility and flexible placement.

Main Results and Discussion

Performance data for eight models (9000–9080) show nitrogen output ranging from 34 to 1,120 L/min, matching inlet air flow rates of 75 to 2,080 L/min.
All units maintain particulate levels below 0.01 μm, zero suspended liquids or phthalates and a dew point of –40 °C.
They operate reliably between 5 °C and 30 °C at inlet pressures of 125–145 psi, with no electrical power required beyond the compressed air supply.

Benefits and Practical Applications

• Continuous gas delivery on demand without cylinder changeover.
• Cost savings over bottled gas and reduced carbon footprint.
• Low maintenance due to robust engineering and easy filter replacement.
• Quiet, compact and mobile design suits multi‐lab installations.
• High purity safeguards sample integrity in QA/QC and research settings.

Future Trends and Opportunities

Integration with laboratory network controls and remote monitoring is anticipated to optimize uptime and service scheduling.
Advances in adsorbent materials could further enhance throughput and purity at lower inlet pressures.
Modular systems may expand to support additional gas types for multi‐gas generation platforms.

Conclusion

The Infinity 90 Series offers a reliable, efficient and eco‐friendly nitrogen supply for a range of evaporation and concentration instruments.
Its scalable models, strong purity performance and minimal maintenance requirements make it a compelling alternative to conventional gas supply methods.
