COA Field-by-Field Review Before Batch Release | Sulan Peptide Official

peptide COAHPLC puritybatch verification

Before any research peptide leaves quarantine, the Certificate of Analysis should be checked as a controlled record—not as marketing support text.

Identity check first: COA product naming must match the catalog listing and the printed vial label, including salt form and mg strength notation.

Lot or batch codes are the only reliable link between a physical vial and analytical data; enter them into LIMS with receipt date and requester.

Test dates and laboratory names show whether the report is current enough for your institutional QA window.

Method notes matter: HPLC UV wavelength, column chemistry, and gradient style help you compare lots across purchasing cycles.

Treat a purity percentage without chromatogram context as incomplete evidence when lots will support publishable assays.

Where available, MS identity (MALDI-TOF or ESI) strengthens confirmation beyond composition tables—especially for longer sequences.

Residual solvent or water lines affect reconstitution math; capture them when your protocol doses by precise molarity.

If endotoxin or bioburden limits appear, decide whether your sterile workflow requires those fields before release.

When Janoshik task data is published, verify task number and unique key from the COA library on sulan-peptide.shop before signing release.

Keep lots quarantined until a named reviewer signs the COA package into the project archive.

Store approved PDF files beside freezer inventory records for the same lot.
