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

• General-purpose columns exhibiting extremely low bleed
• Ideal for many GC-MS applications, including pesticides, PCB congeners (e.g., Aroclor mixes), PAHs
• Unique selectivity
• Temperature range: 30 to 360 °C
• Low-polarity proprietary phase

This combination of column characteristics assures Rxi® columns will have long lifetimes.

Improvements in polymer synthesis and tubing deactivation enable 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.

Restek has also developed a stable, reproducible manufacturing process, so that Rxi® columns will meet your needs every time you install a new column.
