Not all high purity gases are created equally
By their very nature, ultra-high purity gas users can’t tolerate impurities, however achieving 100% purity in a packaged gas isn’t something that is currently possible. While 99.9999% is close, even then there are some impurities present, the important question then becomes what those impurities are. With some being far more detrimental to common UHP applications than others; moisture, oxygen and total hydrocarbons are typically the worst. The internal purification system in a BIP® technology cylinder effectively removes these potentially damaging impurities prior to gas leaving the cylinder, most of the impurities in BIP® technology gases are nitrogen which is typically not harmful.
