Certified Reference Materials CRM Round Robin Characterized Polymers 


Certified Reference Materials(CRM) are highly characterized polymers resulting from round robin experiments at certified laboratories, and subject to certification by the German Federal Institute for Materials Research and Testing (BAM). The CRM quality certificates are full reports with the results of the different characterization methods.

Measurements of CRM are documented using statistically re-calculated data from many laboratories and methodologies: GPC; on-line and off-line GPC-Light Scattering; and on-line and off-line GPC - 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.  View here an example CRM Certificate.

Below is the CRM standard we offer:
