The Growing Demand for Nitrogen
Nitrogen is indispensable in numerous laboratory processes. It is used in gas chromatography, liquid chromatography-mass spectrometry (LC-MS), and as a carrier gas in many other analytical techniques. Its inert nature makes it ideal for creating controlled environments, preserving samples, and ensuring the accuracy and reliability of experimental results.
As laboratories strive for greater efficiency and precision, the demand for high-purity nitrogen has increased. Traditionally, nitrogen has been supplied in gas cylinders or bulk liquid form, but these methods have significant drawbacks, including supply chain logistics, storage challenges, and safety concerns. This is where nitrogen generators come into play.
Nitrogen Generators and Their Advantages
Nitrogen generators are devices that produce nitrogen gas from compressed air on-site, providing a continuous supply of nitrogen at the required purity levels. These systems use technologies such as pressure swing adsorption (PSA) or membrane separation to filter out oxygen and other gases, delivering nitrogen that meets the stringent requirements of modern laboratory applications.

We discuss the benefit provided by nitrogen generators across several pages on Organomation.com but below is a quick summary:
Cost Efficiency of Generators Over Cylinders
One of the most compelling reasons for the shift towards nitrogen generators is cost efficiency. Traditional nitrogen supply methods involve recurring costs for purchasing, delivering, and storing gas cylinders or liquid nitrogen. In contrast, nitrogen generators represent a one-time capital investment with minimal ongoing operational costs. Laboratories can produce nitrogen on-demand, eliminating the need for expensive and time-consuming gas deliveries.
Continuous Supply of Nitrogen Gas
Nitrogen generators provide a continuous and reliable supply of nitrogen, ensuring that laboratory operations are never disrupted due to gas shortages. This reliability is crucial for laboratories with high nitrogen consumption or those conducting long-term experiments. The ability to produce nitrogen on-site also reduces the dependency on external suppliers and mitigates risks associated with supply chain disruptions.
Enhanced Laboratory Safety
Handling and storing high-pressure gas cylinders or liquid nitrogen pose significant safety risks. Accidents related to gas leaks or improper handling can lead to serious injuries and even fatalities. Nitrogen generators enhance safety by reducing the need for high-pressure storage and minimizing the risk of leaks. Additionally, on-site nitrogen generation means that laboratories no longer need to manage the logistics of transporting hazardous materials.
Reduced Environmental Impact
Environmental sustainability is a growing concern across all industries, and laboratories are no exception. Nitrogen generators contribute to environmental conservation by reducing the carbon footprint associated with the production, transportation, and disposal of gas cylinders. By generating nitrogen on-site, laboratories can significantly cut down on emissions and contribute to greener operations.
