Wavelength Optimized dn/dc Measurement

(PresseBox) (Berlin, )
TESTA Analytical Solutions e.K has introduced new laser options for its HK Series differential refractometer to enable precise determination of specific refractive index increment (dn/dc) at the same wavelength as the light scattering application under investigation.Light scattering is a tried and trusted method for measuring molecular weight and therefore a widely used tool for analyzing biopolymers, polymers and proteins. Most labs combine light-scattering detectors with chromatographic techniques such as Gel Permeation Chromatography / Size-Exclusion Chromatography (GPC/SEC). When using a GPC/SEC system with advanced detectors knowing the exact concentration of the sample at each data slice is very important. Accurately determining
