Retatrutide LC-MS: Identity Confirmation
ShiLai™ Healthcare performs LC-MS (liquid chromatography-mass spectrometry) identity confirmation on every batch of Retatrutide. LC-MS provides molecular mass data that confirms the compound is Retatrutide and not a different peptide or impurity.
How LC-MS Identifies Retatrutide
LC-MS measures the molecular mass of the compound by ionizing the peptide and detecting the mass-to-charge ratio (m/z) of the resulting ions. The measured molecular mass is compared to the theoretical molecular mass of Retatrutide. A match confirms identity.
LC-MS and HPLC Together
LC-MS identity confirmation and RP-HPLC purity testing are complementary analytical methods. HPLC tells you how pure the sample is; LC-MS tells you what the compound is. ShiLai™ Healthcare performs both on every Retatrutide batch.
