Nitrogen solutions for laboratory use
Laboratory Nitrogen Generator for On-Site High Purity Nitrogen for reliable lab processes
In modern laboratory environments, precision and control are essential for achieving reliable analytical results and maintaining sample integrity. Even minimal exposure to oxygen or moisture can lead to oxidation, contamination, or degradation of sensitive compounds.
A laboratory nitrogen generator enables laboratories to produce nitrogen on-site, ensuring a continuous and controlled supply of nitrogen gas without relying on external deliveries or traditional nitrogen cylinders. This eliminates the risks associated with cylinder handling, supply interruptions, and fluctuating gas quality.
Presscon is a specialist in advanced solutions for on site nitrogen generation in laboratory applications. Our systems deliver ultra high purity nitrogen with residual oxygen levels below 1 ppm (quality <6.0), ensuring consistent performance in even the most demanding processes. Each nitrogen generator for laboratory use is custom-engineered using High-Performance Pressure Swing Adsorption (HP-PSA) technology and manufactured in-house, guaranteeing reliability, flexibility, and long-term efficiency.
How does a laboratory nitrogen generator work?
A nitrogen generator for laboratory environments produces nitrogen by separating it from compressed air using advanced adsorption technology. Presscon’s systems are based on High-Performance Pressure Swing Adsorption (HP-PSA), a highly efficient method for on-site nitrogen production.
The process begins with compressed air, which naturally contains nitrogen, oxygen, and trace gases. This air is first filtered to remove contaminants such as oil, dust, and moisture, ensuring optimal system performance.
The filtered air then passes through vessels filled with Carbon Molecular Sieve (CMS). These materials selectively adsorb oxygen molecules under pressure, allowing nitrogen to pass through as the primary output gas. By alternating between adsorption and regeneration cycles, the system ensures a continuous and stable nitrogen supply.
A nitrogen gas generator for laboratory applications can deliver nitrogen purity levels ranging from 95% to 99.9999%, depending on the specific requirements of your processes. This flexibility makes the system suitable for both general laboratory use and highly sensitive analytical techniques.
A nitrogen generator laboratory system integrates seamlessly with existing compressed air infrastructure and delivers nitrogen at controlled pressure, flow rate, and purity levels. This ensures reliable operation of laboratory instruments such as LC-MS, GC systems, and sample preparation equipment.
Why high purity nitrogen is essential in laboratory operations
Nitrogen is widely used in laboratories because of its inert properties. By using a laboratory nitrogen generator, laboratories gain full control over gas quality and availability, improving both safety and performance.
Key benefits include:
- Prevents oxidation of sensitive samples, reagents, and chemical compounds
- Eliminates moisture build-up in analytical systems and storage environments
- Provides a stable, inert atmosphere for reproducible analytical results
- Reduces the risk of flammable atmospheres through controlled oxygen displacement
- Eliminates cylinder deliveries, handling risks, and supply interruptions
- Ensures consistent nitrogen purity for validated analytical methods
- Reduces operational costs compared to cylinder or liquid nitrogen supply
A nitrogen generator for laboratory applications supports efficient workflows while maintaining high standards of accuracy and safety.
Applications of a nitrogen gas generator in the laboratory
A nitrogen gas generator for laboratory use supports a wide range of laboratory processes where controlled atmospheres and high-purity nitrogen are required.
Nitrogen as carrier and auxiliary gas for LC-MS
Liquid chromatography-mass spectrometry (LC-MS) systems depend on a stable supply of dry, high-purity nitrogen. Nitrogen is used as curtain gas, nebulizer gas, and auxiliary gas to support ionization and analysis.
Variations in gas purity or pressure can directly impact measurement accuracy. A laboratory nitrogen generator ensures a constant nitrogen supply with residual oxygen levels below 1 ppm, eliminating inconsistencies caused by cylinder changes and supporting validated analytical performance.
Storage of chemicals and pharmaceutical compounds
Sensitive chemicals and pharmaceutical products require controlled storage conditions. A laboratory nitrogen generator provides an inert atmosphere that protects against degradation, ensuring long-term stability and product quality.
Nitrogen as carrier gas for gas chromatography (GC)
In gas chromatography (GC), nitrogen is used as a carrier gas to transport samples through the analytical column. Consistent flow and purity are critical for accurate separation and detection.
A nitrogen generator laboratory system provides stable nitrogen conditions, ensuring reproducible results while eliminating the risks of supply interruptions and contamination.
Inerting of gloveboxes and reactor systems
For handling reactive or oxygen-sensitive materials, gloveboxes and reactor systems require an inert atmosphere. A laboratory nitrogen generator continuously supplies nitrogen to displace oxygen, ensuring safe and controlled conditions.
Blanketing of sensitive samples, reagents, and solvents
Nitrogen blanketing protects chemicals and solvents from exposure to oxygen and moisture. A nitrogen generator for laboratory maintains a stable protective layer of nitrogen, extending shelf life and preserving chemical stability.
Cell Culture incubators and biological processes
In biological applications, nitrogen helps control oxygen levels and maintain stable conditions for cell growth and processing. A nitrogen generator laboratory system supports improved cell viability by reducing oxidative stress during handling and sorting processes.
