The molar masses of gelatin and succinylated gelatin were determined before and after TNBS-derivation by size exclusion chromatography coupled with multi angle laser light scatting (SE.

This paper introduces a way that is used to directly measure molecular weight of semifinished product of transparent shock resident butadiene-styrene copolymer by laser light scattering apparatus at three angles and size-exclusion chromatography together substituting traditional Ubbelodhe viscometer used to indirectly measure molecular weight.

Objective To determine the molecular weight(Mr) and its distribution of hyaluronic acid(HA) by the combination of multi-angle laser light scattering instrument and size exclusion chromatography(MALLS-SEC).
