Characterized before
it reaches the catalog.
No lot is added to inventory until an independent laboratory has returned a full analytical panel. Purity is determined by reverse-phase HPLC, identity is confirmed by mass spectrometry, and each batch is tied to its own archived certificate.

The panel we run on every lot.
Reverse-phase HPLC
Chromatographic purity determined against certified reference material. The purity figure printed on every certificate comes from this method.
Mass spectrometry
Molecular identity verified through mass-to-charge analysis, confirming the compound in the vial matches its published sequence.
Net peptide content
The measured peptide mass per vial, distinct from gross fill weight, so reconstitution math starts from an accurate figure.
Endotoxin (LAL)
Each lot is screened for bacterial endotoxins to a defined internal threshold using the Limulus amebocyte lysate assay.
Appearance & solubility
Visual inspection of the lyophilate and a reconstitution check are performed on every lot before it is released to inventory.
Trace metals
Elemental contaminants are screened against internal specification limits appropriate for research-grade material.
Lot-level documentation
Every batch is assigned a unique lot identifier tied to its certificate, so paperwork always maps to the exact vial in hand.
How a lot moves from synthesis to your bench.
Manufactured to specification
Each compound is produced against a written internal specification and lyophilized to a shelf-stable powder, sealed under conditions that limit light and moisture exposure.
Independent characterization
A representative sample from every lot is submitted to an external laboratory for HPLC purity and mass-spec identity. Analysis is never performed in-house.
Certificate archived
Once results are returned, the certificate is filed against the lot identifier and made retrievable through the COA library before the material is added to the catalog.
Release & dispatch
Vials are inspected, sealed, and dispatched, with the matching certificate accessible from your account for reference at any point.
What the certificate shows.
A certificate is only useful when the numbers on it can be traced back to a single lot. Every Lumina COA ties measured results to a batch identifier you can look up at any time.
- HPLC purity against certified reference material
- Mass-spec identity and observed molecular weight
- Endotoxin result and unique lot identifier on every document
