Exsil 80 Amino is a silica-based HPLC stationary phase with an 80 Å pore size and an aminopropyl (NH₂) bonded surface, specifically designed for the separation of polar compounds and carbohydrates. The controlled pore structure provides a high surface area, enabling efficient analyte interaction and high chromatographic efficiency for small-molecule applications.
The aminopropyl functionality offers strong polar interactions and exhibits weak anion-exchange behavior, allowing Exsil 80 Amino to be used in normal-phase HPLC, HILIC-type separations, and mixed-mode chromatography. This makes the phase particularly suitable for compounds that show insufficient retention on conventional reversed-phase columns.
Exsil 80 Amino delivers reproducible retention, sharp peak shapes, and reliable performance in both routine analysis and method development.
Exsil 80 Amino provides reliable polar selectivity, high efficiency, and versatile chromatographic performance, making it a robust solution for polar compound and carbohydrate separations in HPLC.
