WebMeasurement of Molecular Weight. GPC for the analysis of hydrophobic polymers has traditionally been conducted using a differential refractive index detector (RID) because many synthetic polymer compounds don’t have the functional groups for UV absorbance and the solvent for GPC mobile phase such as tetrahydrofuran (THF) and N,N … WebDec 3, 2010 · Abstract. An innovative approach is presented to interpret the refractive index of binary liquid mixtures. The concept of refractive index "before mixing" is introduced and shown to be given by the volume-fraction mixing rule of the pure-component refractive indices (Arago-Biot formula). The refractive index of thermodynamically ideal liquid ...
