Selection of column and mobile phase eluent/buffer is a crucial step in chromatographic method development. The introduction of new column technologies requires a continuous performance evaluation enabling the deployment of improved chromatographic screening workflows. Consequently, the development of a universal method that could be used across different column chemistries and mobile phase pH ranges would be highlighted as advantageous. Herein, we introduce a single generic probe developed via software-based modeling that delivers excellent results for the separation of a standard multicomponent mixture across a wide range of stationary phases under different pH and temperature conditions. This approach has been applied to interrogate the performance and stability of multiple columns (C18, Cyano, Phenyl Hexyl, PFP, Polar-embeded, and other stationary phases) using an automated ultra-high-pressure liquid chromatography screening system illustrating its practicality and effectiveness.
