Polyacrylamides

Polyacrylamides (PAMs) have many different applications because of their high viscosity. For every application it is crucial to be able to understand how molar mass and molar mass distributions of PAMs relate to product performance. The combination of a size-exclusion chromatograph (SEC) and a multi-angle light scattering (MALS) detector has become an indispensable tool for determining absolute molar masses and their distributions. In this application note, we report the characterization of a PAM sample.
