Low molecular weight polystyrene characterized by SEC-MALS
22 Jul 2020This application note highlights that the fundamental physical principles of light scattering employed in a DAWN® or miniDAWN® multi-angle light scattering (MALS) instrument enable low molecular weight materials to be characterized effectively without the need for column calibration or reference standards. Thanks to their advanced electro-optical design, samples with molecular weights below two thousand Daltons can be measured easily and with remarkable precision
