A Certificate of Analysis (COA) is a document that reports the results of testing performed on a specific batch of material. It ties a batch number to the methods and results recorded for that batch.
When reviewing a COA, researchers typically confirm that the batch number matches the label on their material, note the test date, and review the reported identity and purity results along with the methods used.
Our COA Library organizes documentation by product format so the right document is easy to locate.
