Scope

This standard describes the preparation of mixed gas for calibration using the principle of osmosis, which is a dynamic gas distribution method. The concentration range of the required components in the mixed gas is 10^-9～10^-5 (volume ratio), and the accuracy of the component concentration can reach 2%. In fact, the concentration unit can also be expressed in micrograms per cubic meter. Since it is difficult to keep the concentration of the mixed gas stable in such a low concentration range, it is required that the mixed gas for calibration must be prepared immediately before use, and the pipeline for delivering the mixed gas should be as short as possible.
