Stability at pH Extremes

Phenomenex introduced Gemini-NX C18, the next generation in its family of chromatography media for use in demanding environments. In addition to strong hydrophobic selectivity and high loading capacity, it delivers a significant increase in stability, for more predicable separations and longer column life. The new media features advanced Twin-NX (Two-in-One) technology, which grafts additional silica-organic layers on the surface of the internal base silica. The advanced NX process uses cross-linked ethane groups to reinforce the silica and extend the performance to a pH range of 1 to 12. Gemini-NXs stability translates to a longer product life and reduces downtime required for column switching.
