Frequently Asked Questions
Quick references for what each test means.
What is HPLC-UV purity testing?
High-Performance Liquid Chromatography (HPLC) separates the peptide from related impurities based on how strongly each molecule interacts with a chromatographic column. A UV detector quantifies each separated fraction, and the total peptide peak area divided by all peaks yields the purity percentage.
What does LC-MS confirm?
Liquid Chromatography–Mass Spectrometry (LC-MS) confirms the peptide's molecular identity by measuring its exact mass-to-charge ratio. This verifies the peptide is what it claims to be — not a related molecule with a similar chromatographic profile.
Are all my orders from this exact batch?
Not necessarily — batches are rotated as inventory moves. Check the batch code on your vial against the test history above to find the matching certificate. Every batch we sell has been independently tested.
