Certamer methodology
What we test, what we document, what we claim.
This page describes the Certamer documentation chain in full: what a certificate of analysis contains, how a lot moves through its lifecycle, how any holder of a Certamer document can verify it, and how white-label branding interacts with underlying data. It also states plainly what we do not claim.
Anatomy of a Certamer CoA.
Every production lot receives its own certificate. Values are reported for the specific lot — never inherited from a product line or a previous batch.
| Field | Method | What it establishes |
|---|---|---|
| Identity | ||
| Identity confirmation | Mass spectrometry (MS) | Observed mass matches the theoretical mass of the stated peptide sequence. |
| Lot number | Serialized per production batch | Binds the document to one physical batch. Printed on every vial in the lot. |
| Quality | ||
| Purity | HPLC, area-percent | Chromatographic purity of the lot against the ≥99% release specification. |
| Endotoxin | LAL assay | Bacterial endotoxin level of the lot, reported in EU/mg. |
| Physical | ||
| Appearance | Visual inspection | Description of the lyophilized cake or powder against the reference description. |
| Net content | Gravimetric | Stated fill mass per vial for the format shipped. |
In plain terms: mass spectrometry confirms the vial contains the stated compound, HPLC confirms purity against the ≥99% release specification, and LAL confirms endotoxin is below release limits — all for the specific lot you receive.
EVERY PRODUCTION LOT SHIPS WITH THIRD-PARTY ANALYSIS. ANY SAMPLE OR DEMONSTRATION DOCUMENT IS MARKED "SAMPLE DATA — PENDING THIRD-PARTY LAB REPORT".
The lifecycle of a lot.
A lot number is assigned at production and follows the batch to the end of its life. Nothing ships outside this chain.
Verify a document in one field.
The verification lookup exists so a CoA cannot be quietly altered after the fact. Enter a lot number and the lookup returns the registered record for that lot — compound, format, and the analytical values on file. If a document in your hands disagrees with the lookup, trust the lookup and contact us — if the discrepancy is on our side, we will make it right.
- ›Public: no login is needed to verify a lot.
- ›Canonical: the lookup record is the source of truth for a lot's analytical values.
- ›Persistent: lot records stay queryable after a lot sells out or expires.
Branding never touches the data.
White-label partners can generate CoAs carrying their own logo and company block. The policy governing those documents is short and absolute:
What client branding changes
- Logo and company block in the document header
- Document styling within the fixed template
- Contact details shown for the distributing brand
What client branding never changes
- Analytical values — rendered from the original lot record, not editable
- Lot number, compound identity, format, and test methods
- The Certamer provenance line, which persists on every generated document
- Verifiability — every white-label CoA resolves to the same lot record at the public lookup
What we do not claim.
Precise documentation requires precise limits. For the avoidance of doubt:
- Certamer products are for laboratory research use only. They are not for human or veterinary use, and nothing on this site describes effects, dosing, or administration in humans or animals.
- Certamer is not a pharmaceutical manufacturer. We do not claim GMP certification, FDA approval, or FDA registration.
- Partner laboratory names and report numbers appear on every certificate of analysis. We will publish the laboratory roster on this page as production lots come online. We never present sample or placeholder figures as test results — sample documents are labeled "SAMPLE DATA — pending third-party lab report".
- Products are sold exclusively to verified businesses. We decline orders that fail verification.
