美國聚合物標準品公司推出Dextrans 葡聚糖標準品
Dextrans 葡聚糖標準品
（Mp.峰位分子量, Mw.重均分子量, Mn.數(shù)均分子量,Mz.Z均分子量, IV.粘度值）
生物大分子聚合物如多糖,多聚核苷酸和膠原蛋白等,具有分子大小不均一的特點:
重均分子量（Weight-average Molecular Weight,Mw）：聚合物中用不同分子量的分子重量統(tǒng)計的平均分子量。 ， Wi ：相應的分子所占的重量分數(shù)。
數(shù)均分子量 (Number-average Molecular Weight,Mn)：聚合物中用不同分子量的分子數(shù)目統(tǒng)計的平均分子量。 ， Ni ：相應分子所占的數(shù)量分數(shù)。
