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
- General-purpose columns
- Temperature range: −60 to 330/350 °C (bleed tested temperature/maximum operating temperature)
- Ultra-low bleed
- Exceptional inertness
- Reproducible performance, column after column
- Nonpolar phase; Crossbond® 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.
