The first digit of the classification indicates the number of nines purity (for example, N3.0 = 99.9% purity) and the second digit is the number following the last nine (for example N4.8 Nitrogen has a guaranteed minimum purity of 99.998% and a corresponding maximum impurity level of 0.002% or 20ppm).
Our HiQ high purity gases are suitable for any application where impurity control is important, for example: chromatography, process controls, pharmaceutical applications or gas detection.
