We are currently evaluating how often we will need to send out our N2 from our N2 generator for purity testing. Right now I'm suggesting either quarterly or bi-annually, though Management is asking if we could test annually.
We calibrate our N2 Generator Weekly and have annual Preventative Maintenance performed on the generator by the Manufacturer. This gas is used as a processing aid and does make direct contact with our product (liquid consumable). I can't seem to find any data showing harmful biproducts of N2 generation. Thoughts or suggestions greatly appreciated.
