High purity liquid nitrogen is an extremely pure cryogenic gas with a wide range of industrial applications. It is regulated by the standard GB/T 8979-2008 and has a remarkable purity level of ≥ 99.999%. This ultra-high purity ensures minimal impurities, making it suitable for sensitive processes where even trace contaminants could have significant adverse effects. It is typically supplied in two main forms: tank gas supply and Dewar gas supply, both of which facilitate large-scale storage and transportation.
