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
