High-Purity Hydrogen refers to hydrogen gas that has been refined to achieve exceptionally low levels of impurities. Purity levels are often expressed as a percentage or in terms of “nines” (e.g., 99.999% = 5N).
| Chemical Name | Property | Purity |
| High purity Hydrogen | Non-toxic and non-flammable, highly stable | ≥99.999% |
