How to verify a peptide COA before a research order
A practical process for checking product identity, batch details, analytical methods and document consistency.
Start with the document identity
Check the product name, batch reference, format and report date. The information should match the quotation and the material under review.
Review the analytical context
Read the reported HPLC or identity method, sample reference and result units. Ask for clarification when a document does not identify the tested batch.
Keep a traceable record
Store the COA with the quotation, product specification and dispatch record so your laboratory can review a repeat order consistently.
Continue your review
Compare the record with your laboratory's own procurement requirements, then request the relevant product and batch details.
