Calibration gas mixtures are produced according to Technical Requirements number 6-16-2956-92 “Calibration gas mixtures. Technical standard conditions”.
Calibration gas mixtures are received by mixing of initial pure gases in required proportion. There are more than 700 types of two-component and multicomponent calibration gas mixtures on the basis of oxygen, hydrogen, nitrogen, argon, helium, hydrocarbon, carbon oxide, sulfur-containing components, ammonia. Range of component fraction in mixture – 0,00005 …99,0%. Composition, concentration, limit of allowance, cylinder requirements are defined additionally.
