Products are released against a documented identity and purity specification. Whatever is measured for a given batch is recorded in a Certificate of Analysis (COA) tied to that batch and lot number, so a claim about material can always be traced to the document that supports it.
What a COA records
- Identity confirmation for the labeled compound
- Measured purity, and the analytical method used to determine it
- Batch and lot numbers for traceability
- Test and release dates
A purity figure on a product page is a specification — the minimum the material is released against. The measured figure is the one on the COA, and the two are not interchangeable.
Every product vial carries a QR code that resolves to the COA for its batch, and you can also search any batch number on our Lab Testing page.
The documents published on this site today are sample files. They show the format and the traceability chain but contain no laboratory results, and each one is marked as a sample in its title and filename.
