Documented at every step
Quality and Certificates of Analysis
Every lot is analysed by an independent laboratory for identity, purity and endotoxin levels before release. Certificates of Analysis are issued by accredited U.S. laboratories.
Tested for every batch
- Identity — confirmed by mass spectrometry (MS)
- Purity — determined by high-performance liquid chromatography (HPLC), reported at ≥99%
- Endotoxin levels
Finding the certificate for your lot
Each product page links to the Certificate of Analysis for that batch. Where a lot-specific certificate has not been published yet, the product link returns to this page — send us your order number or lot reference and we will supply the document.
Certificates pending publication
Batch certificates are published as soon as the independent laboratory releases them. A product page that links here does not yet have a lot-specific certificate attached.
