Mixed-Mode HPLC Columns

Overview

The column you need with multiple functionalities

Do you want to separate ionic and hydrophobic analytes in a single run? Separate polar, nonpolar, and ionizable compounds in a single analysis and achieve baseline separation of challenging polar analytes without derivatizing using a mixed-mode HPLC column. The stationary phases of Thermo Scientific mixed-mode columns combine reversed phase, ion-exchange, and/or HILIC selectivity. This eliminates the need for column switching, ion-paring, and using columns in series. Easily optimize selectivity by adjusting mobile phase buffer concentration, pH, and solvent content to improve chromatographic separations and increase productivity.

Mixed-mode HPLC columns are well-suited for retaining ionic analytes, including pharmaceutical drugs and their counter ions. Mixed-mode liquid chromatography does not require the use of ion-pair reagents in the mobile phase, significantly improving mass spectrometry (MS) compatibility.
