Every lot we ship is accompanied by an independent Certificate of Analysis. This post walks through what that document contains and how we generate it.
Identity by mass spectrometry
Each batch is submitted for mass-spectrometry identity confirmation, matching the observed mass against the expected molecular weight of the reference material.
Purity by HPLC
Reverse-phase HPLC is used to quantify chromatographic purity. The resulting percentage is reported directly on the certificate, alongside the method parameters.
Batch traceability
Lots are coded so a certificate can always be matched back to the exact production run, supporting reproducible analytical work.
