Supply of Calibration Gas with Calgaz cylinder
Calibration gas, also known as specialty gas or calibration gas mixture, is a precisely mixed and certified blend of gases used as a reference standard to ensure the accurate functioning of analytical instruments, particularly gas detectors and analyzers.
Calibration gases can be single-component (e.g., pure carbon monoxide) or multi-component mixtures (e.g., a mix of methane, carbon monoxide, and hydrogen sulfide). Common gases used in calibration mixtures include:
Carbon Monoxide (CO)
Carbon Dioxide (CO2)
Hydrogen Sulfide (H2S)
Methane (CH4)
Oxygen (O2)
Nitrogen Dioxide (NO2)
Sulfur Dioxide (SO2)
Ammonia (NH3)
Hydrogen (H2)
Various hydrocarbons (e.g., propane, butane, pentane)
The specific mixture depends on the type of instrument being calibrated and the gases it's designed to detect.
