Peptide COA Library & Batch Records
Review the batch information currently published for each product. When a public document is not linked, request the available record for the specific compound and lot. Evaluate every report according to the methods and results it actually contains.
What is a COA?
A Certificate of Analysis reports the tests and results recorded for a particular sample or batch. It should identify the lot, date, methods, and issuing laboratory.
Read the Methods
HPLC can report relative purity, while mass spectrometry can support identity. A report does not establish an attribute unless the corresponding test is shown.
