Sample Preparation

Light scattering detectors play an important role in gel permeation chromatography and size exclusion chromatography (GPC/SEC) analysis because of their ability to directly measure molecular weight distribution. Multi angle light scattering (MALS) detectors are often chosen, in some instances because they provide the most accurate data for the measurement of the radius of gyration (Rg), and in others because they have become an accepted industry standard. The launch of Malvern Instruments’ new Viscotek SEC-MALS 20 detector extends commercial choice in this area and draws the technology into the spotlight.
