CALIBRATION GASES
Calibration Gases, also called reference gases and standard gases, belong to gaseous standard material. It is widely used in fields of chemistry, physics, biology and petrochemical engineering. Calibration gases consist of minimum two, and can be as high as 31 components which are based on customers requirements. The method of preparation of calibration gases is gravimetric method in an ISO1/ICE: 17025 certified laboratory.
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 the calibration gases with trace
components like CO, CO2, NO, SO2, they must be stored in
aluminum alloy cylinders For calibration gases with corrosive
components like SO2, H2S, NO, NO2, CL2, NH3, PH3, etc,
with a concentration of under 10ppm, aluminum alloy cylinders
with internal coating must be used. Most calibration gases require
use of stainless steel gas valves such as CGA 660, CGA 890, CGA350, etc.
