Nitrogen
Nitrogen constitutes 78% of the atmosphere and is a constituent of all living tissues. Under normal conditions, nitrogen is a colorless, odorless and tasteless inert gas which has no toxic properties and is slightly lighter than air. As a liquid at -320 ºF it has a water-white appearance and must be handled with care due to its low temperature.
Liquid Nitrogen is classified as Type II by the Compressed Gas Association (CGA). CGA-10.1, Type II, Grade L or The National Formulary Specs (similar to USP) are considered commercial liquid nitrogen standards.
