Independent analytical testing
Know what's in every vial.
Enter the code on a certificate to pull up the third-party HPLC and mass-spec results filed for that vendor's batch — chromatogram, results, and method.
The problem
A certificate is only as good as the lab behind it.
Most certificates of analysis are scanned PDFs — cropped, unsearchable, and impossible to trace to a source. We host the result itself, tied to a batch, so anyone holding the vial can verify it.

How it works
From sealed sample to public record.
STEP 01
Intake
A vendor ships a sealed sample from one production batch. It's logged against a unique code and a chain-of-custody entry.
STEP 02
Analysis
Reverse-phase HPLC for purity, LC-MS for identity, Karl Fischer for water, and LAL for endotoxins — each against a defined specification.
STEP 03
Verification
The result is published to the code. Anyone can pull up the chromatogram, the results table, and the exact method used.
Methods
Every number ties back to an instrument.
RP-HPLC
Purity & impurities
C18 reverse-phase separation with UV detection at 214 nm.
LC-MS
Identity confirmation
Observed mass matched to the expected molecular ion.
Karl Fischer
Water content
Coulometric titration for residual moisture.
LAL
Bacterial endotoxin
Limulus amebocyte lysate assay, reported in EU/mg.
