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

• Convenient 2 m length is ideal for use as a secondary column in GCxGC analyses
• Engineered to be a low bleed GC/MS column
• Excellent inertness for active compounds.
• General-purpose columns, low bleed
• Temperature range: −60 to 350°C
• Reproducible performance, column after column
• Low-polarity phase; Crossbond® 1,4-bis(dimethylsiloxy)phenylene dimethyl polysiloxane

In addition to outstanding performance, this combination of column characteristics assures Rxi® columns will have long lifetimes.

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.

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.
