Media for selectivity and capacity at
extreme pH
Gemini-NX delivers a significant increase in stability for more predicable separations and longer column life, as well as strong hydrophobic selectivity and high loading capacity
Phenomenex introduces Gemini-NX C18, the next generation in its family of chromatography media for use in demanding environments 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

New chiral HPLC/SFC columns from Phenomenex
Lux columns are offered with two chiral stationary phases (CSPs), both of which use coated derivatised cellulose as the chiral selector
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-NX's stability translates to a longer product life and reduces downtime required for column switching.
The extended pH range allows greater flexibility in mobile phase modifications and more control over retention and selectivity of ionisable compounds.
Because the majority of pharmaceutical compounds possess ionisable functional groups, Gemini-NX has wide applications in drug discovery, method development and large-scale purification.
"Phenomenex was a pioneer in pH-LC separation technology with our original Gemini offering," commented Jason Lam, brand manager for Phenomenex.
"Our leadership tradition continues with Gemini-NX, which delivers significant performance advancements.".
