标准摘要
[中文适用范围]： 本文件规定了使用尺寸排阻色谱法 (SEC) 测定聚合物的平均分子量和分子量分布的通用方法。 如果使用 ISO 16014-2 尺寸排阻色谱法与光散射检测 (SEC-LS) 中所述的 SEC 技术之一，则根据使用聚合物标准品构建的校准曲线计算平均分子量和分子量分布。 [外文原描述]： 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.
