HPLC Purity Analysis
High-Performance Liquid Chromatography resolves the main peak and quantifies what else is present, which is how a purity figure is actually arrived at.
Identity Verified
Certificate of Analysis
Proof that what's printed on the label is what's in the vial — issued per lot, by a laboratory that doesn't work for our marketing department.
The Document, Not The Summary
A Certificate of Analysis is the lab's own report on a specific batch. We publish it whole rather than quoting the one number that flatters us.

What Gets Tested
Mass Spectrometry
Molecular weight confirmation — the check that the compound is the one named on the label and not a mass-alike.
Identity Confirmation
The result is compared against the characterised reference for that compound before the lot is released.
Batch Records
Identity, content and appearance are recorded against the lot number at release, so the paperwork and the vial can't drift apart.
Finding Your Certificate
1
Scan Or Type The Lot
Every label carries a QR and a printed lot number. Either one opens the page for that batch.
2
Open The Report
The lot page links the certificate itself — the laboratory's document, not a retyped extract.
3
Check It Against The Vial
Confirm the lot on the report matches the lot on your label, then read the purity figure and test date.
COA Questions
What is a Certificate of Analysis?
It's the report an analytical laboratory issues for a specific batch, covering identity and purity. Ours carry the HPLC content result and the mass-spec identity confirmation for that lot.
Where do I find the COA for what I bought?
Scan the QR on the vial, or enter the printed lot number on the verify page. Both resolve to that batch's own certificate. Support can send it directly if you'd rather ask.
How do I read one?
The figures that matter are purity percentage, the molecular weight confirming identity, appearance, and the date of test. Check the lot number on the report against the one on your vial first — that match is the whole point.
Which laboratory tests your batches?
Independent analytical labs that we pay for testing and that have no stake in the outcome — Freedom Diagnostics for our current lots. We name the lab on the certificate rather than referring vaguely to "accredited partners".
Is every batch tested?
Every lot we list is tested before release. If a lot doesn't meet the purity standard it isn't sold, and it doesn't quietly reappear at a lower price.
Need a specific certificate?
Send support your order or lot number and we'll send the batch documentation back.
