CromSil™ Prime (Mixed-Mode HPLC) Columns

Advanced Multi-Mode Selectivity for Complex Separations

CromSil™ Prime

The Prime series of mixed-mode HPLC columns is engineered to handle complex separations by integrating multiple retention mechanisms within a single stationary phase. These columns efficiently separate polar, non-polar, hydrophilic, hydrophobic, organic, and inorganic compounds, making them ideal for pharmaceutical, chemical, food, and research applications.

With a unique combination of reversed-phase, ion-exchange (cationic and anionic), hydrogen bonding, and HILIC interactions, Prime columns allow for highly selective, efficient, and robust separations, eliminating the need for multiple columns or complex mobile phase modifications.
