Detection Orthogonality in Macromolecular Separations. 2: Exploring Wavelength Orthogonality and Spectroscopic Invisibility Using SEC/DRI/UV/FL

We continue herein the exploration of detector orthogonality in size-based macromolecular separations. Previously [5], the sensitivity of viscometric detection was juxtaposed to that of differential refractometry (DRI) and light scattering (LS, both static and dynamic), and it was shown that viscometry is a truly orthogonal detection method to both DRI and LS. Here, via the size-exclusion chromatography (SEC) analysis of blends of polystyrene...
