Liquid Chromatography

Will aerosol-based detectors ever meet all the needs of the pharmaceutical industry?

Get the most out of Pittcon, Atlanta with our top picks from the sessions.

Triple detection GPC/SEC combines measurements from multiple detectors to offer not only increased amounts of data, but also increased amounts of information, which is made available by the combination of different detectors (and unobtainable using individual detectors separately). The theory of triple detection GPC/SEC is described here.

This application note describes the analyses of a variety of aqueous (water-soluble) cellulose derivatives using the OMNISEC triple detection system and the subtle, yet distinct differences between these different derivatives that can be parsed out by the OMNISEC system

In this application note, molecular weight data from the Viscotek SEC-MALS 20 is combined with measurements of Rg and IV to study the structure of different polysaccharides including pullulan, dextran, hydroxypropyl cellulose (HPC), pectin and gum Arabic. The differences between conformation and Mark-Houwink plots are also studied.
