es, this product is suitable for quantitative analysis, such as content or assay tests. The % purity is available on the Certificate of Analysis. The purity is calculated using the following equation:
% purity = (100 - ROI - LOD - H2O - RS) x ((100 - TCI)/100)
Where:
TCI = Total Chromatographic Impurities
LOD = Loss on Drying
H2O = Water content determined by Karl Fischer analysis
ROI = Residue on Ignition
RS = Residual Solvents

Description générale
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards
Application
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Remarque sur l'analyse
These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
Autres remarques
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

I ordered this material to use as a certified reference material for GPC determination. The certificate of analysis has a purity but not an average Mw, Mn or Mp. Can I please get the Mp for this standard so that I can use it for my purpose?
1 answer-
This product is intended for use as a USP, EP, and BP traceable secondary standard in compendial methods. The testing performed is for purity by HPLC, moisture determination, and residue analysis. The agency specific monographs do not include GPC analysis or specifications for Mn, Mp, and Mw. Please see the link below to review a sample of lot specific Certificate of Analysis for a product that may be more suitable for GPC analysis.
