Understanding the Effect of Molecular Weight and Structure on the Performance Characteristics of Cellulose Derivatives Using OMNISEC

A key family of molecules of interest to the pharmaceutical industry is those derived from cellulose such as hydroxyethyl cellulose and others. This application note describes the analyses of a variety of aqueous (water-soluble) cellulose derivatives using the OMNISEC triple detection system. It demonstrates the subtle, yet distinct differences between these different derivatives that can be parsed out by the OMNISEC system.
