Common questions about batch documentation
Is a certificate of analysis the same as “third-party tested”?
No. “Third-party tested” is a claim; a certificate of analysis is a document. The difference that matters is whether the certificate names a specific lot, carries a date and a certificate number, and can be checked with the issuing laboratory. A report that does not name the lot cannot be matched to the vial in your hand.
Can I read the report before I order?
Yes. Every published report is in the open batch COA library before the batch is listed for sale. Nothing is held back until after purchase.
What if the lot number on my vial does not match any published report?
Then the documentation does not cover what you received, and you should ask the supplier why before anything else. Email us and we will resolve it.
Does a high purity number mean the material is what the label says?
Not on its own. Purity by HPLC describes the proportion of detected peak area; identity is a separate determination, typically by mass spectrometry. Both belong on a complete report, which is why the full certificate matters more than a single headline percentage.
