Application Notes: General

The recently introduced 1 mm YMC-Triart C18 UHPLC column was used for the high sensitivity LC–MS screening of six antineoplastic drugs.

A YMC-Triart C18 and a YMC-Triart SIL column were used in RP and NP mode, respectively, for the analysis of four different phosphoramidites.

Mipomersen was analyzed by LC–HRMS using a biocompatible YMC-Triart C8 metal-free column, ensuring symmetric peaks, high sensitivity, and no carryover effects.

The separation of three cell-penetrating peptides (CPPs) was performed using a YMC-Triart C18 UHPLC column, providing sharp peaks for a fast analysis in under 4 min.

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.
