Nitrogen (N2)

Nitrogen is a non-corrosive, inert gas and is compatible with most common metals, provided it is used with equipment suitable for high-pressure applications.

Characteristics:

Odorless and colorless, non-toxic, does not support combustion

In high concentrations, it can cause asphyxiation

Inert, dry, and slightly soluble

Applications:

Cleaning, protection, inerting (reactors and storage tanks), dilution of unwanted gases or vapors

Cooling and freezing of food, modified atmosphere packaging, food storage (controlled atmosphere), food inerting

Chemical and petroleum industry

Food industry

Pipeline cleaning

Rocket propulsion

Liquid transfer

Auxiliary gas for laser cutting of stainless steel, aluminum, and non-metallic materials

Thermal processing to protect against reactive metals

Electrochemical analysis

Maintenance of dry and inert atmosphere concerning chemicals during storage, reaction, and processing

Extension of the lifespan of rubber

Expansion-contraction of metals. Liquid nitrogen (-196 °C) reduces the physical dimensions of a material placed in it, allowing it to be connected to other materials and sealed when it returns to normal temperatures and expands

Storage of medical or research samples, such as blood, plasma, and sperm
