What every Certificate of Analysis covers.
A full analytical panel, run by accredited US labs. Here's what each result tells you.
Identity
Confirmed three ways — retention time, spectral match, and co-elution. It's exactly the compound on the label.
Potency — assay
Assay confirms the vial holds the stated amount, down to the microgram. You get the concentration you paid for.
Purity
Screened for byproducts and related impurities against a ≥99% standard. No surprises in the vial.
Endotoxins
Bacterial endotoxin testing to research-use standards. A clean, documented profile.
System suitability
The method and instrument pass control checks before any result counts. Results that actually mean something.
Accuracy & precision
Spike-recovery and replicate CV% confirm the numbers are reproducible. Measured, then re-measured.
