*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengthsmay have a slightly reduced
maximum temperature.
Rxi®-XLBColumns
(fusedsilica)
(lowpolarityproprietaryphase)
• General purpose columns exhibiting extremely lowbleed. Ideal formanyGC/MS
applications, includingpesticides, PCB congeners (e.g.Aroclormixes), PAHs.
• Unique selectivity.
• Temperature range: 30 °C to360 °C.
Improvements in polymer synthesis and tubing deactivation enable us tomake 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, coupledwith inertness, lowbleed, andhigh thermal stability,make
Rxi®-XLB columns ideal for analyzing semivolatile compounds indrinkingwater (e.g.,
USEPAMethod525).
