Intrinsic Viscosity Analysis

When to use a Light Scattering in High Temperature GPC for Polyolefins

A Light Scattering detector is as powerful as it is challenging to use for high-temperature applications, such as GPC/SEC. It is the only detector that can provide absolute molar mass results and Long Chain Branching calculations without depending on columns . . . read more »

Solvent-Free vs Solvent-Based Intrinsic Viscosity Testing: Choosing the Right Tool for PET

  As sustainability goals push the plastics industry toward greener processes, solvent-free Intrinsic Viscosity (IV) testing – based on melt-flow analysis – has gained attention. Such methods promise fast, eco-friendly testing with results equivalent to solvent-based IV methods. But are . . . read more »
