The Standard for ph Method Development

The Standard for ph Method Development High Efficiency Excellent Lifetime ph Stable - www.phenomenex.com/gemini

U.S. Patent No.,, Setting the Standard for ph Method Development Gemini columns are rugged reversed phase HPLC columns that offer extended lifetime at extreme ph conditions and excellent stability for reproducible, high efficiency separations. Take full advantage of high and low ph conditions (ph -) to manipulate selectivity Expect longer column lifetime with patented TWIN-NX technology Phase NX-C C-Phenyl C Description The most rugged Gemini column, offering times the durability of previous generation hybrid columns A low bleed phenyl phase. For UV and MS detection, which offers an aromatic selectivity complementary to C phases Selectivity, high structural integrity and increased loadability for preparative and purification applications in pre-packed columns and bulk media USP Classification L L L For analytical and preparative separations of basic and acidic compounds TWIN (Two-In-ne) Technology Gemini C and C-Phenyl During the final stage of silica manufacturing a unique silica-organic layer is grafted to create a completely new composite particle. nce the internal base silica is unaltered by this manufacturing process, the particle retains its mechanical strength and rigidity along with excellent efficiency, while the silica-organic shell protects the particle from chemical attack. Second-Generation TWIN-NX Technology Gemini NX-C TWIN-NX technology uses an improved patented organo-silica grafting process which incorporates highly stabilizing ethane 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.
