How can I verify the purity of gas from my nitrogen generator?
July 8, 2022
Pneumatech's nitrogen generators are used in multiple applications in the food and beverage industry, laser cutting equipments, electronics and much more. The purity levels in each of these applications varies and every product range has to be tested to determine its' purity levels and performance resulting in documented purity certificates. But how can I verify the purity of gas from my nitrogen generator?
- 2008/84/EC grade 99.0% N2 – Food Safety – (Purity criteria on food additives other than colours and sweeteners (August 27th, 2008)
- EU pharmacopoeia 01/2008 12470 M grade 99.5% N2
- USP-NF33 (7727-37-9) – United States Pharmacopoeia – 01/12/2015
Why are purity certificates necessary?
Every application that requires the use of nitrogen gas needs the nitrogen at a specific purity level for optimal performance.
For some examples: laser cutting metal typically uses >99,9% Nitrogen, metal heat treatment typically uses 99.5% purity, food packaging ranges from 99.5% to 99.9% and wine-making uses anywhere from 99.5% to 99,999% purity during various stages of the wine-making process. While these percentage differences may seem small, 0.001% makes a big difference in the process and Nitrogen purity levels and performance. Every application will also need specific pressure requirements, flow levels and PDP as well.
Purity certificates are often presented during job bidding or used for verification that a unit can perform to certain specs before being installed in a facility.
