Abstract

Size exclusion chromatography calibrations for polystyrene and poly(ethylene glycol) standard samples in the molecular weight range of (600-11000) have been obtained in tetrahydrofuran. The Kuhn-Mark-Houwink-Sakurada constants of poly(ethylene glycol) in tetrahydrofuran were determined, and poly(ethylene glycol) chromatograms were evaluated according to primary and universal calibration methods. The molecular weights determined from universal curves were substantially lower than those obtained from primary curves. The Coll and Prusinowski universal calibration procedure gave better results than the calibration of Benoit et al.

聚乙二醇的粒径排除色谱法

在四氢呋喃中获得了分子量范围为(600-11000)的聚苯乙烯和聚乙二醇标准样品的尺寸排除色谱校准。测定了四氢呋喃中聚乙二醇的Kuhn-Mark-Houwink-Sakurada常数，并根据一级和通用校准方法对聚乙二醇色谱进行了评价。用通用曲线测得的分子量明显低于用原始曲线测得的分子量。Coll和Prusinowski通用校准程序比Benoit等人的校准结果更好。
