该方法用于测定烯烃石脑油中C5和较轻的二烯烃、单烯烃和石蜡。还鉴定了分解的炔烃和分解的C6烃，包括分解的二烯烃。该方法适用于最终沸点为260℃或更低的具有类似基质的选择性加氢工艺进料、产品和其他工艺流。如果样品中存在在规定条件下不能从色谱系统中洗脱的成分，则不进行测定。任何化合物的检测下限为0.01质量%。附录描述了分析液化石油气样品方法的扩展

This method is for determining C5and lighter diolefins, mono-olefins, and paraffins in olefinic naphthas. Resolved acetylenes, and resolved C6hydrocarbons, including resolved dienes, are also identified. The method is applicable to selective hydrogenation process feeds, products, and other process streams with similar matrices having a final boiling point of 260 degrees C or lower. Components that do not elute from the chromatographic system under the specified conditions, if present in the sample, are not determined. The lower limit of detection for any compound is 0.01 mass %. TheAppendixdescribes an extension of the method to analyze LPG samples
