规定的方法适用于液化石油气中碳氢化合物的定量测定，不包括浓度低于O，1％（m/m）的组分。它适用于丙烷，丁烷及其商业混合物的分析，其可包括饱和和不饱和的C2，C3，C4和C5烃。它不适用于“在线”色谱

The method specified applies to the quantitative determination of hydrocarbons in liquefied petroleum gas, excluding components whose concentrations are below O,1 % (m/m). It is applicable to the analysis of propane, butane and their commercial mixtures which may include saturated and unsaturated C2, C3, C4 and C5 hydrocarbons. It does not apply to "on-line" chromatography.
