*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced
maximum temperature.
Rxi®-XLB Columns (fused silica)
(low polarity proprietary phase)
• 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 °C to 360 °C.
Improvements in polymer synthesis and tubing deactivation enable us 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 semivolatile compounds in drinking water (e.g.,
US EPA Method 525).
