Application Note: Quality control of polyamides using the DS2500 Solid Analyzer
7 April 2020

Functional group and viscosity analysis (ASTM D789) of polyamides can be a lengthy and challenging process due to the sample’s limited solubility. This application note from Metrohm demonstrates that the DS2500 Solid Analyzer, operating in the visible and near-infrared spectral region (Vis-NIR), promises a cost-efficient and fast solution for a simultaneous determination of the intrinsic viscosity as well as the amine, carboxylic, and moisture content in polyamides.
