Peptides with acidic side chains, deamidation, or phosphorylation can interact with metal surfaces, leading to poor peak shape and analyte recovery. Altura columns feature Agilent's innovative Ultra Inert technology. The advanced coating blocks active metal sites, ensuring an inert flow path while maintaining the strength, pressure tolerance, and consistency of a traditional stainless steel HPLC column.

This application note shows how the right column chemistry and mobile phase modifier can dramatically improve impurity profiling for complex peptides like semaglutide. By comparing seven reversed-phase columns under both TFA and FA conditions, the findings highlight the standout performance of the AdvanceBio Peptide Plus column, especially in LC/MS workflows using FA.
