COMBINED NITROGEN/AIR GENERATORS

2 gases solutions in one box to supply your analytical instrument

F-DGSi offers the most extensive range of combined nitrogen/air generators for applications such as GC, LC-MS, MP-AES and PEGASUS. We can offer these generators with or without a compressor. If you are interested in improving your laboratory with a combination of Nitrogen and air, contact us today or browse our wide range of combined N2/Air generators.

What is a nitrogen/air generator and how it works?

Combined Nitrogen/Air generators are a safer and more convenient alternative to using gas cylinders. Every time you change a gas cylinder, you take the risk of polluting your gas line with contaminants and impurities. Whereas with a combined nitrogen/air generator once installed, it will always provide the correct, consistent, worry-free gas purity to suit your needs. But how does a combined nitrogen/air generator work?

The combined Nitrogen/Air generator use pressure swing adsorption technology (PSA) to produce pure nitrogen gas and an additional bed of activated alumina for air purification

Benefits of a nitrogen/air generator against gas cylinders

Once installed in your laboratory, the combined nitrogen/air generators provide a constant supply of nitrogen and air with permanent purity from the ambient atmosphere, 7 days a week, 24 hours a day. This can provide a nitrogen purity from 99% up to 99,9995% depending on the generator model and an Air purity up to 0.01 ppm HCs and – 50°C air dewpoint. This gas supply will last as long as your instrument needs it without contamination.

For added safety, our gas generators store very little nitrogen and air internally. Nitrogen and Air is produced at low pressure unlike traditional gas cylinders.

Our combined gas generators work continuously to deliver nitrogen and Air at all times, eliminating the risk of running out of gas during your analysis. Don’t waste time ordering, receiving, storing and changing cylinders! Concentrate on what is really important for the laboratory, i.e. the analysis. Also, this two gases solution in one box allow you to save space in your lab.

With a combined nitrogen/air generator, you replace obsolete cylinder technology with constant production that can save you up to 50% of the cost of gas. This gives you a much faster return on investment than gas cylinders.

Combined Nitrogen/Air generators are a much more environmentally friendly and sustainable source of gas supply than gas cylinders. Indeed, gas cylinders have high energy requirements such as: the CO2 emission involved in delivery and recovery and the energy consumption involved in manufacturing the gas.
