Lab testing and certificates

Certificates of Analysis are available on request: email us the product and lot number. Published certificates are in the COA Library.

What a certificate covers

A Certificate of Analysis is the record for one lot. When a laboratory issues it, the certificate is the place to read identity and the purity figure, and the method the laboratory names, such as HPLC or mass spectrometry. This page does not invent a method, a purity number, or a laboratory name for a lot that has no certificate posted.

How to request one
