Certificates of Analysis
Every Atlas lot is tested by an independent laboratory before release. Enter your lot number to pull the report for that exact production run.
Lot lookup
The lot number is printed on the vial label directly beneath the strength.
What is on the certificate
Lot header
Compound name, lot number, manufacture date and testing laboratory. Always confirm the lot matches the number printed on your vial before reading further.
HPLC purity
Peak-area percentage for the target compound. Atlas targets ≥99%. Review the chromatogram for a single dominant peak on a flat baseline.
Mass spectrometry
Measured molecular weight versus the theoretical weight of the sequence. This confirms identity — purity alone does not.
Water and residuals
Karl Fischer moisture content plus residual solvent results where applicable. Excess moisture shortens shelf life.
