TESTA Analytical has developed a 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 is 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 COMBO-TWO MALS/DRI detector package brings together 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 COMBO-TWO is simple to use, operating from room temperature up to 80° C, with high thermal stability.
