Chlorofluorohydrocarbons for industrial use — Determination of inert gas content — Gas chromatographic method — General principles

Describes a method applicable to products having inert gas content equal to or greater than 0,005 % (V/V). The principle is based on detection of inert gas from test portion s taken from the liquid or gaseous phase and analysis under such conditions that none of the gases are retained irreversibly by the stationary phase.
