Description
Gemini columns are rugged reversed phase HPLC columns that offer extended lifetime at extreme pH conditions and excellent stability for reproducible‚ high efficiency separations.
TWIN-NX technology uses an improved patented organo-silica grafting process which incorporates highly stabilizing ethylene cross linking. These organic groups are evenly incorporated into the grafted layers on the silica surface while maintaining a pure silica core. This not only provides resistance to high pH attack‚ but also maintains the high efficiency and mechanical strength of a silica particle.
