highly characterized polymers certified by BAM
European Reference Materials (ERM)/ Certified Reference Materials (CRM) are highly characterized polymers certified by German Federal Institute for Material Research and Testing (BAM). Their reported molar mass result from round robin experiments at certified laboratories.
The ERM’s/ CRM’s quality certificates are full reports with the results of the different characterization methods:
GPC, Light Scattering and Viscometry.
Further, the certificate includes additional non-certified data, (MALDI-ToF; NMR; DSC and in some instances Rheology data) to provide the most sophisticated set of documentation for a particular polymer available worldwide.
