NITRO-GEN+ Nitrogen Generator

Significance of the Topic

Effective and reliable nitrogen supply is critical in analytical chemistry for applications including sample evaporation and LC-MS. On-site gas generation enhances laboratory safety by removing high-pressure cylinders and ensures continuous operation without interruptions, supporting data quality and workflow efficiency.

Objectives and Overview

This document presents the NITRO-GEN+ Nitrogen Generator (Model NA1935), developed for integration with Organomation nitrogen evaporators and LC-MS systems. It aims to deliver a self-contained nitrogen source with high purity and constant flow, reducing operational risks and maintenance requirements.

Used Instrumentation

• NITRO-GEN+ Nitrogen Generator (Catalog NA1935)
• Dual oil-free compressors (high- and low-pressure stages)
• Carbon Molecular Sieve (CMS) adsorption modules

Methodology and Technical Features

The generator combines a two-stage compressor design with CMS technology to separate nitrogen from ambient air. Key performance parameters include:

• Flow rate: up to 35 L/min
• Purity: up to 99% at flow ≤ 25 L/min, 98% at >25 L/min
• Dewpoint: -50 °C
• Output pressure: 0–8 bar
• Warm-up time: 20 minutes
• Noise level: 55 dBA at 1 m
• Power: 110–240 V, 50/60 Hz, 1800 W
• Certifications: CE, FCC, UL/CSA compliant

Main Results and Discussion

The NITRO-GEN+ delivers a stable, uninterrupted nitrogen flow that meets or exceeds typical laboratory demands for purity and rate. The dual-compressor layout reduces mechanical stress, prolonging service life and lowering maintenance intervals. Operation at ambient pressure and temperature removes safety hazards linked to cylinders and dewars.

Benefits and Practical Applications

• Plug-and-play installation simplifies integration into sample prep and LC-MS workflows
• Continuous supply avoids downtime during cylinder exchanges
• Quiet operation supports a comfortable laboratory environment
• Reduced operational costs through longer compressor life and elimination of cylinder handling

Future Trends and Potential Uses

On-site gas generation is trending towards smarter, networked devices offering remote monitoring and predictive maintenance. Advances in adsorption materials may further increase purity and efficiency. Integration with laboratory automation platforms will streamline sample workflows and resource management.

Conclusion

The NITRO-GEN+ generator provides a safe, efficient, and high-performance nitrogen source for modern analytical laboratories, enhancing throughput, reliability, and safety while reducing costs and environmental impact.
