Molecular Weight and Structure Analysis of Controlled Drug Delivery Polymers.

The article presents information about analysis of molecular weight and structure of polymers used in controlled drug delivery systems. Analysis of the raw polymers and the polymer-drug bioconjugates is critical to both the development and production of the materials. Gel permeation chromatography (GPC or SEC) is commonly used for the analysis of many synthetic and natural polymers including proteins. Triple Detection GPC system can give the true molecular weight of any drug delivery polymer directly, without relying on comparison with standards.
