Liquid Nitrogen and Nitrogen Gas (N2) What is nitrogen? PurityPlus® carries liquid nitrogen and compressed nitrogen gas at a variety of concentrations and purities. Nitrogen gas is an odorless, colorless, chemically inert gas that comprises about 78% of the air we breathe, making it the most common element in Earth’s atmosphere. Although nitrogen is viewed as inert, it is essential to the majority of plants’ processes of ingesting water, minerals, and nutrients from soil, as well as acting as an ultraviolet and radiation filter for the Earth. Nearly all commercial nitrogen is generated through the process of liquefying air and distilling it into its three major parts: nitrogen (78%), oxygen (21%), and argon (0.9%). Liquid nitrogen uses and nitrogen gas uses Today, nitrogen is commercially used in a wide range of applications. These include: concrete cooling, chemical processing, metal production and fabrication, construction, and several other miscellaneous applications. Ultra-High purity and Ultra-Carrier Grades of nitrogen are utilized as blanketing agents in chemical and pharmaceutical processing, and are also commonly applied as carrier gases in both gas and liquid chromatography.
