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.

A smart poly(acrylic) acid shows promise as a carrier to improve anticancer drug action, says Alison Maniego

The Uwe D. Neue award recognizes the impact that breakthrough work by industrial scientists has on analytical science. 2015’s recipient is Mark Schure – and here’s why.

Nearly half a century ago, J. Calvin Giddings published a letter that laid out his ideas for a new separation strategy. It resulted in a collection of techniques known as field-flow fractionation (FFF)

Accurate measurement drives progress in science in immeasurable ways. Here, we celebrate a year’s worth of advances in The Analytical Scientist Innovation Awards 2014. What impact will these 15 TASIA winners have on your field?
