How one product delivers a deeper understanding of the physical structure of a compound than traditional GPC/SEC characterisation
T
riple Detection GPC/SEC is a tried and tested technique for the complete and accurate characterisation of
macromolecules including proteins, polysaccharides, and synthetic polymers. Most often the technique combines both light scattering and viscometer detectors with a refractive index (RI) detector to deliver invaluable molecular weight and structure information to researchers. A powerful new triple detector for Gel Permeation Chromatography / Size Exclusion Chromatography (GPC/SEC) called Trinity has been released by Testa Analytical. [uses software]
The product is aimed at
researchers whose focus is not limited to molecular weights but needs a deeper understanding of the physical structure of a compound then the powerful combination of Diff erential
Refractive Index (DRI), Multi-Angle Light
Scattering (MALS) and Viscometer detectors.
ABSOLUTE VALUES FOR MOLECULAR WEIGHTS The Trinity Triple Detector delivers absolute values for molecular weights plus

absolute intrinsic viscosity and precise Mark-Howink coeff icient data. This enables users to unlock information about both chain fl exibility and molecular density. As a result, the determination of macromolecular branching can be based on solid data rather than assumed or projected data, opening the way to a deeper understanding of the macromolecule under study.
INDEPENDENT TEMPERATURE CONTROL
Each detector in the Trinity has independent temperature control to ensure that high levels of precision
and reproducibility can easily be achieved from one day to the next. This triple detector GPC/SEC platform is supported by a software suite that combines operation that aims to be intuitive with all the necessary tools to generate and present results from the collected raw data. Drawing upon over 30 years of experience, Testa Analytical has established itself as a creator and supplier of innovative, high performance chromatography instrument kits, and detectors with many end user and OEM clients around the world. ■
