Analytical methods
Identity and purity,
measured.
High-performance liquid chromatography with UV detection, coupled with mass spectrometry (LC-MS), is the primary analytical language on Simple Peptide Certificates of Analysis.

01
What HPLC-UV reports
HPLC separates components in the tested sample. UV detection supports a purity assessment for the reported peak profile under the laboratory method in effect for that COA. Molecule-specific results vary; the lot record controls.
-
02
What LC-MS confirms
Mass spectrometry supports identity confirmation by relating observed mass information to the expected peptide. COA language typically states identity confirmed when the independent laboratory’s criteria are met.

03
How researchers should read the COA
Treat the applicable lot Certificate of Analysis as the controlling document for the material supplied. Compare product name, lot identifiers, reported purity, and identity statements before experimental use in a qualified laboratory setting.
