Methods for sampling and analysis of ambient air Method 2.2: Preparation of reference test atmospheres-Compressed gas method
|Publication Date:||6 May 2016|
This Standard sets out a method for the preparation of reference test atmospheres containing known concentrations of determinand(s), using a calibration gas dilution method.
The method is applicable to components that do not react with each other, the cylinder walls or the dilution gas, and that remain totally vaporized in the cylinder at all pressures and temperatures anticipated during the preparation and use of the reference test atmosphere.
