Testa Analytical Launch New GPC/SEC Combination Detector

Jan 11 2023

Combination GPC/SEC Detector delivers outstanding macromolecular characterisation

Testa Analytical has developed a new Multiple Angle Light Scattering/Differential Refractive Index (MALS/DRI) combination detector package for more demanding Gel Permeation Chromatography (GPC/SEC) applications.

Delivering absolute molecular weight data from small to large molecules, MALS has established itself as a tried and trusted GPC/SEC detection technique for polymer, protein, and polysaccharide applications.

However, the most accurate and sensitive results can be only achieved by pairing MALS with a DRI detector, designed to deliver concentration information detected at the very same wavelength.

The new COMBO-TWO MALS/DRI detector package from Testa Analytical brings together a perfectly matched combination of a high performance 7-angle MALS and an ultra-stable DRI detector - both designed to optimally operate using an integral 640nm light source. Fully compatible with all commercial GPC/SEC systems, the unique COMBO-TWO offers the lowest possible delay volume between the MALS and DRI detectors enabling exceptional results to be routinely obtained. Operating from room temperature up to 80°C, with high thermal stability, COMBO-TWO is simple to use - just inject your sample into the low-volume flow cell to obtain highly accurate and reliable MALS and DRI data.
