CALIBRATION GAS

Calibration gas, also called reference gas and standard gas, belongs to gaseous standard material. It is widely used in fields of chemistry, physics, biology and engineering surveying. Calibration gas can be consist of two or more components which is based on customers' requirements. And the method of preparation of calibration gases is gravimetric method.


In order to ensure the stability of calibration gases, we need to consider the effect of the cylinder material on the gases. Normally, for most of constant calibration gases, they can be stored in normal steel gas cylinders. But for the calibration gases with trace components like CO, CO2, NO, SO2, they must be stored in normal aluminum alloy cylinders. For calibration gases with corrosive components like SO2, H2S, NO, NO2, CL2, NH3, PH3, etc., and the concentration of these components is under 10ppm, they must be stroed in internal coating aluminum alloy cylinders. And the valves should be used stainless steel gas valves.
