ISO 16014-2:2003规定了使用尺寸排除色谱法(SEC)测定聚合物平均分子质量和分子质量分布的方法。用通用校准曲线代替传统校准曲线计算平均分子质量和分子质量分布。本试验方法被归类为ISO 16014-1中所述的相对方法,但通过该方法计算的平均分子质量和分子质量分布等于或几乎等于绝对值。
ISO 16014-2:2003 specifies a method for determining the average molecular mass and the molecular mass distribution of polymers using size-exclusion chromatography (SEC). The average molecular mass and the molecular mass distribution are calculated using a universal calibration curve instead of the conventional calibration curve. This test method is classified as a relative method as described in ISO 16014-1, but the average molecular masses and molecular mass distributions calculated by the method are equal to, or nearly equal to, the absolute values.
