How to Read a RUO Certificate of Analysis | Peptide Purity Checklist

RUO COA checklist for Canadian laboratories: identity fields, lot matching, HPLC purity, fill-mass separation, and verification references.

A RUO Certificate of Analysis is a documentation record for research peptides Canada labs. It helps a lab compare identity fields, lot details, purity reporting, and issuing-laboratory references before filing an order record.

This checklist is for Research Use Only laboratory documentation. It is not for human or veterinary use, and it is not health, therapeutic, or dosing guidance. Buyers must be 21+.

Start with identity fields

A lab should first check the compound name, nominal fill mass, physical form, lot identifier, issuing laboratory, and any accession or report reference. The certificate should match the vial label and the order record. Published certificates are listed on the COA index.

For GHK-Cu examples, compare the catalogue fields on GHK-Cu 50mg and GHK-Cu 100mg, then read the Canada sourcing notes at buy GHK-Cu Canada and GHK Cu peptide Canada research overview.

Lot match between vial label and COA

The lot or batch field is the bridge between the physical vial label and the certificate record. If the lot field does not match, treat the certificate as a separate record and do not attach it to that vial in your lab file.

HPLC purity versus fill mass

HPLC purity and fill mass are separate documentation fields. HPLC purity reports the analytical result for a tested material; it does not, by itself, establish the filled mass in a vial. Check the vial label, SKU, order record, and any lot-matched certificate fields where published.

Verification checklist references

Use Freedom Diagnostics peptide COA verification and Janoshik peptide COA as checklist references for field-by-field review. Then return to the COA index to compare the published document with the product record.

Catalogue context
