Frequently Asked Questions
How is Nitrogen used in food preservation?
Nitrogen prevents oxidative damage that leads to food spoiling.
What is the difference between NF and USP?
NF (National Formulary) and USP (United States Pharmacopeia) designations indicate that the product is safe for medical use. They were two separate regulatory bodies that merged in the 1970s. Some medical gases are designated NF, some are USP, and some are the merged USP-NF. NF, USP, and USP-NF gases are all regulated by the FDA (Food and Drug Administration).
What nitrogen cylinder sizes does General Air carry?
