本文件规定了使用尺寸排除色谱法（SEC）测定聚合物平均分子量和分子量分布的一般方法。 如果使用ISO 16014-2至ISO 16014-4中所述的SEC技术之一，则根据使用聚合物标准构建的校准曲线计算平均分子量和分子量分布；如果使用尺寸排阻色谱结合光散射检测（SEC-LS），则根据使用绝对分子量数据构建的校准曲线计算平均分子量和分子量分布，如中所述ISO 16014-5。交叉引用:ISO 16014-4ISO 16014-2ISO 16014-5ISO 472ISO 16014-3购买时可用的所有现行修订版均包含在本文件的购买中。

This document specifies a general method for determining the average molecular weight and the molecular weight distribution of polymers using size-exclusion chromatography (SEC). The average molecular weight and the molecular weight distribution are calculated from a calibration curve constructed using polymer standards if using one of the SEC techniques described in ISO 16014-2 to ISO 16014-4 or from a calibration curve constructed using absolute molecular weight data if using size-exclusion chromatography coupled with light-scattering detection (SEC-LS) as described in ISO 16014-5.Cross References:ISO 16014-4ISO 16014-2ISO 16014-5ISO 472ISO 16014-3All current amendments available at time of purchase are included with the purchase of this document.
