What is the cost of N2 gas in Australia?

ROI for 35 LPM (2.1 m3/hr)

A nitrogen cylinder delivery contract may seem like the easiest way to manage your laboratory budget, however, the purchase of a nitrogen gas generator is a more cost-effective way to secure ongoing nitrogen gas supply. While the initial outlay for cylinders is low, contracts are often subject to regular price increases, as well as hidden costs such as regulator maintenance, delivery, fuel and cylinder & pallet rental charges, which can soon add up. A gas generator offers a more economical solution, typically offering savings versus cylinder supply, within the first year of ownership.

One LC-MS instrument running 8 hours a day, 5 days a week that requires 32 L/min of nitrogen will consume around 4 million liters of nitrogen per year, that is equivalent to approximately 450 cylinders of nitrogen. The table below is a break down the costs associated with ordering 450 cylinders:

ROI for 70 LPM (0.07 m3/min)

For higher flow gas requirements such as higher-end LC-MS, NMR, turbo evaporators, fume hoods, small lab reticulated gas supply, wine making/bottling, micro-breweries & food packaging, liquid nitrogen is a common method for supplying nitrogen. However, consider the following, gas usage for a facility requiring gas on demand 24 hours per day, 7 days a week needing 70 LPM (0.07 m3/min) is equal to 36, 792,000 litres of gas per annum. This equates to 0.105 L N2/min of liquid N2 boil off requirement. Deliveries to the facility for adequate operation would mean a minimum of 63,387 L per year of liquid nitrogen to produce the boil off gaseous nitrogen to meet the facility’s nitrogen demand.

Peak's Genius Series

Peak Scientific’s Genius series is a compressor-based nitrogen generator based on more than a decade’s worth of research and design. Developed for LC-MS applications, the Genius range of nitrogen generators provide a dependable and consistent high purity flow of nitrogen, your gas supply will be available on-demand, 24/7.

Producing your own nitrogen gas with a Genius generator will earn a quick return on investment for your one-time nitrogen generator costs with its low service fees and maximum uptime. Gone will be the days of planning and paying for the delivery, installation and replacement of your cylinder.

On top of the cost savings and convenience, Peak’s Genius generators also offer peace of mind, as safety concerns are mitigated by the extremely low pressure and volume storage, along with inbuilt leak detector technology.

Traditional methods of gas supply have proven to be cumbersome and inconvenient, not only for financial reasons, but also for safety concerns, logistical planning and unreliability in terms of supply and purity. This means the nitrogen generator costs you pay offers unparalleled value for not just your budget, but also for optimum workflow.
