Saving Money with a Nitrogen Generator

Does your lab use nitrogen gas cylinders? If so, you’ve probably considered purchasing an on-site nitrogen generator. You might have also wondered whether it would be worth the investment. Read on to discover what you could save on by making this switch. 

If you’re not currently using a nitrogen generator in your lab, you’re likely to be bound by a contract with a third party gas company not merely to buy nitrogen, but also to pay for the delivery, installation and rent of high pressure gas cylinders or dewars. All these additional charges can quickly add up, particularly when nitrogen gas costs fluctuate and spike due to a disruption or shortage in the supply chain.

Typical 3 year cylinder supply costs for one LC-MS
Year 1 Year 2 Year 3 Total
Cost of gas ($45 per cylinder) $20,250 $20,250 $20,250 $60,750
Cost of cylinder rental
$600 $600 $600 $1,800
Delivery cost ($30 per
delivery of 5 cylinders)
$2,700 $2,700 $2,700 $8,100
Total spend
over 3 years
Compare these costs with the total spend when using Peak Scientific's Genius XE 35 as a standalone nitrogen generator, which can save 51% over 3 years

With a nitrogen generator, you no longer need to buy nitrogen from a third party. Instead, you can simply generate the amount of nitrogen you need, depending on your instrument, meaning the nitrogen supplied to your instrument will be tested to meet the flow rate and purity requirements of the instrument you are using.

Using a nitrogen generator for your applications, the nitrogen produced is supplied from the same air we breathe in amounts based on your instrument’s demand. This means you will not need to pay for delivery and rental costs again. Instead, with a Peak nitrogen generator, you will cut down on nitrogen gas costs by having an unlimited supply of nitrogen at the flow rate and purity that your instrument and application require.


What to Consider when Purchasing a Nitrogen Generator

Nitrogen generators and hydrogen generators

Nitrogen gas requirements vary from one lab to another, and the nitrogen generator you need will depend on your application and instrument. For instance, if you’re using a single LC-MS/MS, then Genius XE 35 would be recommended for your application. However, if you need to supply nitrogen to multiple instruments, where you require higher flow rates or nitrogen for an entire lab’s instrumentation, then an i-FlowLab would be the better option.

Once your nitrogen generator is in place, you can start saving money on extra expenses, as well as administrative and logistical time, not to mention the increased safety from not needing to handle heavy and awkward cylinders around the lab. Having a nitrogen generator on-site will also increase your lab work efficiency in eliminating disruption caused by cylinder swapouts. Why not take control of your own gas supply and stop relying on third parties to buy nitrogen if you can save on nitrogen gas costs with an on-site nitrogen generator?
