What's inside
every CoA.
A batch-specific Certificate of Analysis ships with every order. Here's exactly what it documents.
Label claim verified
HPLC-UV-MSThe CoA reports the total mass of active compound recovered from the vial, in milligrams, and as a percent of the stated label claim. Quantified by HPLC-UV-MS against an authentic reference standard.
On the document:
Compound name, CAS number, label claim, measured mg per vial, % of label, LOQ, method date.
Chromatographic purity
USP/NF 621The area of the compound peak is divided by the total area of all peaks in the chromatogram, expressed as a percent. The full HPLC chromatogram and the mass spectrum compared against the authentic standard are reproduced inside the CoA.
On the document:
Purity %, retention time, chromatogram trace, mass spectrum overlay, identity confirmation.
Endotoxins
USP 85 · LALBacterial endotoxin content per vial, measured in endotoxin units (EU) by the limulus amebocyte lysate (LAL) method. Reported against the limit of quantification so trace results are explicit, not implied.
On the document:
EU per vial, LOQ, method (USP 85), analysis date.
FDA critical metals
USP 233 · ICP-MSArsenic, cadmium, lead and mercury quantified by ICP-MS against certified standards. Each element is reported individually in micrograms per vial, with the limit of quantification shown alongside — not detected means below LOQ, not unmeasured.
On the document:
As, Cd, Pb, Hg results, CAS numbers, μg per vial, LOQ, method date.
Also on every CoA
- Lab number & project ID
- Batch / lot number
- Date received & date issued
- Methods summary & SOP references
- Laboratory director signature
Why Aitrixa
Built for serious
research workflows.
Three reasons researchers reorder from us and refer their colleagues.
Always in stock
Top reference compounds (retinoids, vitamins, peptides) ship the same day. Stock updated weekly.
Cold-chain storage
Lyophilized compounds are held in a dedicated freezer with logged temperature monitoring.
Responsive customer support
Our support team replies within hours. Inquiries are handled by people who know the catalogue and care about getting it right.
On our standard
Research demands certainty. Not approximation. Not vendor assurances without evidence.
Compounds we stock carry batch-specific Certificates of Analysis. If the data doesn't confirm ≥ 99% purity, the batch is destroyed.

Frequently asked
Before you order.
Everything you need to know about ordering reference standards from Aitrixa.
A batch-specific document listing purity (HPLC), identity (HRMS), heavy metals (ICP-MS), endotoxin (LAL), net weight, lot number, and the named analyst who released the batch. Sample available on request.
Shipping is fast — orders are typically fulfilled the same business day if placed before 2pm EST.
Orders are final once shipped, with two exceptions: a wrong product, or one that arrives damaged in transit. In either case, send our support team evidence of the packaging and product within 48 hours of delivery and we'll take care of it.
