What do Rxi columns mean to you? Three things:

  • Ultra-low bleed.
  • Exceptional inertness.
  • Reproducible performance, column after column.

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.

The Rxi-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. Rxi-5Sil MS columns are ideal for GC/MS applications requiring high sensitivity, including use in ion trap systems.
