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.
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.

The role that nanoparticles play in the rapidly developing field of ‘NanoMedicine’ has been discussed previously in Chapter 5. In this Chapter, we review the specific mechanisms by which such nanoparticles are designed and formulated and in which NTA has had a significant part to play.
The ability to quickly and reproducibly measure coffee ground particle size and size distributions is important during grinding operations to ensure that the coffee quality is maintained and that the correct grade is produced. The Mastersizer 3000 and the Funnel Sample Feeder for the Aero S dry powder disperser provides this capability, offering a rapid alternative to traditional sieve analysis.
