Ultra High Purity Gas
Ultra purity gases refer to gases that have undergone rigorous purification processes to achieve extremely high levels of purity by removing impurities and contaminants. These gases are used in various industries and applications where even trace amounts of impurities can have detrimental effects on processes and equipment.
The purification of ultra purity gases involves multiple steps and technologies to achieve the desired level of purity. These steps can include filtration, adsorption, cryogenic distillation, and other specialized techniques depending on the specific gas and impurities involved. The goal is to eliminate impurities such as moisture, oxygen, nitrogen, carbon dioxide, hydrocarbons, and other trace elements to levels well below industry standards.
The precise composition of ultra purity gases depends on the particular gas being purified. Nitrogen, oxygen, argon, and helium are among the most commonly purified gases, with purity levels reaching beyond 99.999% (referred to as “five nines”) and even higher. The remaining impurities in these gases are typically measured in parts per million (ppm) or parts per billion (ppb).
