Learn what certified reference material values establish, how to read uncertainty and traceability, and why a COA alone does not establish CRM status.

Quality & Testing articles from Peptides Centre explain peptide quality markers, COAs, HPLC testing, purity references, lab verification, documentation, and product transparency. This section is designed to help customers understand how to review research peptide quality information and what terms such as Certificate of Analysis, HPLC verified, purity, and batch documentation may mean when browsing peptide products in Canada.
Learn why “not detected” does not mean zero, how detection and quantification limits differ, and what to ask before comparing laboratory reports.
Understand laboratory measurement uncertainty, instrument resolution, calibration and traceability, with a report-review checklist and primary references.
Connect a received peptide lot, its documents and each preparation to the experimental result—and distinguish material records from measurement traceability.
A certificate of analysis, or COA, is a lot-specific summary of test results. It should help a laboratory decide whether a material meets predefined requirements for a particular use. A COA is not a substitute for understanding the test methods, and a polished document is not proof that every relevant quality attribute was measured. The […]
