Rxi® fused silica capillary GC columns are designed specifically for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity.

• Low-bleed, high-thermal stability column—maximum temperatures up to 300 to 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
• Mid-polarity Crossbond® phase

In addition to outstanding performance, this combination of column characteristics assures Rxi® columns will have long lifetimes. The Restek chemists also have developed a stable, reproducible manufacturing process, so that Rxi® columns will meet your needs every time you install a new column.
