Certificates of Analysis
Every production lot is independently analyzed for identity and purity. The certificates below document the testing performed on recent lots. For a specific lot or additional documentation, please contact our support team.
Identity confirmed by mass spectrometry. Purity determined by integration of the HPLC-UV chromatogram at 214 nm.
Copper content confirmed by ICP-MS. Peptide purity determined by integration of the HPLC chromatogram.
Identity and purity confirmed by reverse-phase HPLC against reference standard.
What every Certificate of Analysis covers
- ✓Identity confirmation by mass spectrometry
