midpolarity Crossbond phase

• Low-bleed, high-thermal stability column—maximum temperatures up to 300–320 °C.
• Inert—excellent peak shape for a wide range of compounds.
• Selective—G43 phase highly selective for volatile organics and residual solvents, great choice for USP<467>.
• Manufactured for column-to-column reproducibility—well suited for validated methods.

·         Rxi fused silica capillary GC columns were designed specifically to be the best columns available for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to outstanding performance, this combination of column characteristics assures Rxi columns will have long lifetimes. Restek chemists have also developed a stable, reproducible manufacturing process so that Rxi columns will meet your needs every time you install a new column.
