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. 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.
Low-bleed, high-thermal stability column—maximum temperatures up 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.
