Application Notes: LC

Twenty-eight PFAS in human serum were analyzed using a YMC-Triart C18 column. An automated SPE system was coupled to an online SPE column-switching LC–MS/MS method.

Four hydrophilic dipeptides were separated with excellent resolution using a YMC-Triart SIL column. Even structurally similar dipeptides were separated in under 4 min.

The UHPLC analysis of four cyclic peptides is shown. Based on the hydrophobicity of the peptides, a YMC-Triart Bio C4 UHPLC column was chosen for this application.

The analysis of FMOC-derivatized glyphosate and AMPA in water samples was performed using a YMC-Triart C18 UHPLC column at an elevated pH of 9.5.
