Method of examining purity of dendrimers

摘要

A method of examining the purity of dendrimers is revealed. It comprises steps of measuring a light scattering intensity of a set of pure standards having a specific molecular weight with a static laser light scattering detector by use of flow injection polymer analysis; establishing a scaling relation by doing a regression of a ratio of the light scattering intensity per concentration (I/c) against molecular weight (M.W.); measuring the light scattering intensity of a dendrimer to be tested having the same unit and surface-modified functional group as the set of pure standards, and examining the purity of the dendrimer to be tested according to the scaling relation.

1. A method of examining the purity of dendrimers, comprises the steps of:
(A) measuring a light scattering intensity of a set of pure standards having a specific molecular weight with a static laser light scattering detector by use of flow injection polymer analysis; (B) establishing a scaling relation by doing a regression of a ratio of the light scattering intensity per concentration (I/c) on the molecular weight (M.W.) of the set of pure standards; and (C) measuring the light scattering intensity of a dendrimer to be tested and examining the purity of the dendrimer to be tested according to the scaling relation.
