For gas mixture manufacturing to be a success, there has to be reliable cylinder preparation as well as cylinder surface treatment technology. When it comes to calibration gas or specialty gases, different manufacturers or suppliers apply different types of terminology to their cylinder treatment processes.
The proofs of utility with regard to the gases the prolonged shelf life with good and viable mixtures. An order is placed by the customer with the supplier after all the gas mixture specifications are resolved. Orders can be Placed for catalog mixtures as well as non catalog mixtures. When it is a catalog item, the procedures with regard to production and laboratory regulations are defined and routine. When the mixture is a non catalog item or customized then technical know-how of the supplier comes into play.

Some of the technicality of calibration gases and specialty gas is addressed based on the cylinder material which could be aluminum or steel, the basic process and technology of cylinder preparation, impurities and grades of raw materials, the technology of blending including the measurements and tolerance, the chemical compatibility, certificate of analysis, transportation and storage and laboratory procedures.
There are a number of blending options which include dynamic, gravimetric and volumetric. Out of these methods, gravimetric blending is known for its high levels of accuracy and tight tolerances. Blending takes places only after a suitable cylinder and treatment process is identified. The most challenging chemical components for blending and mixtures are hydrogen sulfide, ammonia, nitrogen dioxide and hydrogen chloride.
