Scope
Main technical content: This document specifies a method for determining permanent gases (hydrogen, nitrogen, oxygen, methane, carbon monoxide, and carbon dioxide) in polymer-grade ethylene and propylene using a gas chromatograph equipped with a helium ionization detector. This document is applicable to the determination of polymer-grade ethylene and propylene with a hydrogen content of not less than 0.1 mL/m3, a nitrogen content of not less than 0.05 mL/m3, an oxygen content of not less than 0.05 mL/m3, a methane content of not less than 0.05 mL/m3, a carbon monoxide content of not less than 0.05 mL/m3, and a carbon dioxide content of not less than 0.05 mL/m3
