U.S. Patent o. 7, 56, 67 Setting the Standard for ph Method Development ugged 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 TWI-X technology For analytical and preparative separations of basic and acidic compounds If Gemini analytical columns do not provide at least an equivalent separation as compared to a competing column of similar particle size, similar phase and dimensions, send in your comparative data within 5 days and keep the Gemini column for FEE. Phase X-C8 C6-Phenyl C8 Description The most rugged Gemini column, offering 5 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 C8 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 TWI (Two-In-ne) Technology 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 TWI-X Technology TWI-X technology uses an improved patented organo-silica grafting process which incorporates highly stabilizing ethane crosslinking. 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.

U.S. Patent o. 7, 56, 67 Virtually o LC/MS Bleed The increased stability of Gemini columns provide the ultra-low bleed profile required for high sensitivity LC/MS applications. The advanced Twin Technology used for Gemini columns limit phase cleavage and stabilizes the silica surface. When compared against a background MS profile, Gemini columns demonstrate virtually no column bleed across a wide mass range. Total Ion Current Extended Column Lifetime The Twin Technology engineering of Gemini provide stability and increased column lifetime. Whether used under isocratic or gradient conditions, Gemini columns out-perform and outlasts ph stable columns. This is illustrated below.
