What purity means in procurement
Purity is a specification and analytical reference. Buyers should compare the ordered specification with the batch document and analytical report.
B2B Peptide Guide
Peptide Purity, HPLC, and MS Guide
Purity and identity documentation helps buyers understand what is being supplied. HPLC and MS reports are commonly requested with peptide COA documents.
How HPLC supports review
HPLC analysis can show chromatogram profile and purity percentage under a specific method. It is helpful for comparing batch documents.
How MS supports identity
Mass spectrometry helps verify molecular weight and supports identity confirmation for the peptide batch.

FAQ
Common questions for procurement, documentation, and factory inquiry teams.
Should HPLC and MS be requested together?
When available, reviewing both can provide a clearer analytical picture.
Can the same purity target apply to every peptide?
Not always. Sequence complexity, scale, and modification can affect feasible purity targets.
Does this article make efficacy claims?
No. It only discusses analytical documentation and procurement review.
