Nitrogen (N₂, R-728) is a colorless, odorless, and inert gas that is non-flammable and non-toxic. It is produced in large volumes by fractional distillation of liquefied air at air separation units. Nitrogen is available in various purity grades, with high-purity nitrogen undergoing additional purification processes. It is supplied in high-pressure cylinders or as a cryogenic liquid.
Recommended regulator: W019130 or W019230 for cylinder use.
APPLICATIONS:
Nitrogen is highly versatile and used across numerous industries:
- In the chemical and petrochemical industries for blanketing, purging, and pressure transfer of flammable substances.
- In food and beverage packaging (Modified Atmosphere Packaging – MAP) to extend shelf life.
- In electronics and semiconductor manufacturing for inert atmospheres.
- In metal processing for heat treatment and cooling.
- In laboratories, medical storage, and biological sample preservation (when supplied as liquid nitrogen).
FEATURES & BENEFITS:
- Inert and non-reactive, ideal for processes that require contamination-free environments.
- Available in multiple purity levels to suit industrial, scientific, and food-grade applications.
- Can be supplied in compressed gas or liquid form depending on application needs.
HAZARDS:
- Asphyxiant at high concentrations – displaces oxygen in confined spaces.
- Cold burns or frostbite risk when handling liquid nitrogen – use protective gear.
- Ensure proper ventilation and safety protocols when using in enclosed areas.
