FAQ - Recycled Helium Grade 5.0

Grade 5 refers to helium with a purity of 99.999%. It is the highest level in our recycled helium range, above our >95% and >99% products. This exceptional purity makes it suitable for all applications involving gaseous helium.

Yes, rigorously so. Once recycled and purified, Grade 5 helium has the same physical and chemical characteristics as helium extracted from the ground. It meets the same industrial standards and can substitute native helium without any adaptation to your equipment or processes.

Helium is a non-renewable natural resource with limited global reserves. Choosing recycled helium extends the lifespan of this rare resource while reducing the environmental impact associated with its extraction. At equal purity and performance, it is the industrially responsible choice.

Every batch is analysed and certified before delivery. The 99.999% purity level is verified through rigorous quality controls throughout the recycling and purification process. A certificate of analysis can be provided on request to meet the traceability requirements of your processes.

Yes! 45-8 ENERGY provides a collection and recycling service for degraded helium. This solution helps you reduce supply costs while recovering value from your residual gas. Visit our “Helium Recycling” page to find out more.

* According to a life cycle assessment conducted in accordance with ISO 14040 and 14044 standards, which compares the recycled European helium offered by 45-8 ENERGY with traditionally imported virgin helium. The impact varies by a factor of 2 to 4 depending on various criteria: distance from the source of degraded helium, volume and purity of the recovered helium, etc.
