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 exhibiting extremely low bleed
• Unique selectivity
• Temperature range: 30 to 360 °C
• Exceptional inertness
• Reproducible performance, column after column
• Low-polarity proprietary phase

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

Improvements in polymer synthesis and tubing deactivation enable Restek to make inert, stable Rxi®-XLB columns especially well-suited for analyzing active, high molecular weight compounds with sensitive GC/MS systems, including ion trap detectors. Excellent efficiency, coupled with inertness, low bleed, and high thermal stability, make Rxi®-XLB columns ideal for analyzing semi-volatile compounds in drinking water (e.g., US EPA method 525).

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.
