Combination Detector Delivers Outstanding Macromolecular Characterisation

The COMBO-TWO Multi-Angle Light Scattering / Differential Refractive Index (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. Delivering absolute molecular weight data from small to large molecules, MALS is recognised as a 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.
