Principles of Triple Detection GPC/SEC

| Sponsored by Malvern Panalytical

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.

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

| Sponsored by Malvern Panalytical

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

Characterizing polysaccharide structure with SEC-MALS and intrinsic viscosity measurements

| Sponsored by Malvern Panalytical

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.

Case study of a semi-pure β-amylase extract

| Sponsored by Malvern Panalytical

The investigative power of multiple detectors. Here, we describe the analysis of a semi-purified protein mixture containing β-amylase. Step-by-step, we show how different properties of the proteins elicit a specific response in each detector and how coupling this data can be qualitatively and quantitatively evaluated.
