This International Standard specifies a gas chromatogrphic method for the determination of hydrocarbon impurities in ethylene for industrial use.
The method is applicable to the determination of the impurities listed in annex B and principally to the determination of
- mathane(CH4)at concentrations greater than 5ml/m3;
- ethane (CH3-CH3)at concentrations greater than 5ml/m3;
- acrtylene(ethyne)(CH≡CH)at concentrations greater than 1ml/m3;
- proylene(CH3-CH2-CH3)at at concentrations greater than 2ml/m3;
- propylene(propene)(CH2=CH-CH3)at concentrations greater than 2ml/m3.
