How to Read a Certificate of Analysis
Purity (%)
The percentage of the target compound vs total sample mass, measured by HPLC. All PepC.Labs products are ≥99%.
Mass Spectrometry
Confirms the molecular identity by measuring exact mass. HPLC tells you how pure, mass spec tells you what it actually is.
Task Number
Janoshik's unique job reference. You can verify any certificate at janoshik.com/verify using the QR code or task number.
Batch Number
Links the certificate to the specific batch of product in your vial. Every batch is tested independently.
