GC COLUMNS | HIGH-PERFORMANCE RXI COLUMNSRxi®-5Sil MSRxi®-5Sil MS StructurexyRxi®-5Sil MS (low polarity Crossbond® silarylene phase; selectivity close to5% diphenyl/95% dimethyl polysiloxane)• Engineered to be a low bleed GC/MS column.• Excellent inertness for active compounds.• General purpose columns—ideal for GC/MS analysis of polycyclicaromatic compounds, chlorinated hydrocarbons, phthalates, phenols, amines,organochlorine pesticides, organophosphorus pesticides, drugs, solvent impurities,and hydrocarbons.• Temperature range: -60°C to 350°C.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 tooxidation. Rxi®-5Sil MS columns are ideal for GC/MS applications requiring highsensitivity, including use in ion trap systems.similar phasesDB-5MS, VF-5ms, CP-Sil 8 Low-Bleed/MSRxi®-5Sil MS Columns (fused silica)(Crossbond ® , selectivity close to 5% diphenyl/95% dimethyl polysiloxane)ID df (µm) temp. limits 15-Meter 30-Meter 60-Meter0.25mm 0.10 -60 to 330/350°C 13605 136080.25 -60 to 330/350°C 13620 13623 136260.50 -60 to 330/350°C 13635 136381.00 -60 to 325/350°C 13650 13653 136970.32mm 0.25 -60 to 330/350°C 13621 136240.50 -60 to 330/350°C 136391.00 -60 to 325/350°C 136540.53mm 1.50 -60 to 310/330°C 13670ID df (µm) temp. limits 10-Meter 20-Meter0.10mm 0.10 -60 to 330/350°C 436010.18mm 0.18 -60 to 330/350°C 436020.36 -60 to 330/350°C 43604freeliteratureRxi ® -5Sil MS:Exceptionally InertColumns for GC/MS andTrace Level AnalysesDownload your free copyfrom www.restek.com.Flyerlit. cat.# GNFL1061Rxi®-5Sil MS with Integra-GuardGet the protection without the connection!• Extend column lifetime.• Eliminate leaks with a built-in retention gap.• Inertness verified by isothermal testing.Description qty. cat.# price15m, 0.25mm ID, 0.25µm Rxi-5Sil MS w/10m Integra-Guard Column ea. 13620-127 enquire30m, 0.25mm ID, 0.25µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13623-12430m, 0.25mm ID, 0.25µm Rxi-5Sil MS w/10m Integra-Guard Column ea. 13623-12730m, 0.25mm ID, 0.50µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13638-12430m, 0.25mm ID, 0.50µm Rxi-5Sil MS w/10m Integra-Guard Column ea. 13638-12730m, 0.32mm ID, 0.50µm Rxi-5Sil MS w/5m Integra-Guard Column ea. 13639-125 enquireIntegra-Guard built-in guard columnPhases currently available asIntegra-Guard columnsRtx ® -1Rtx ® -5Rtx ® -5MSRxi ® -5Sil MSRtx ® -1301Rtx ® -624Rtx ® -1701Rtx ® -VolatilesRtx ® -20Rtx ® -35Rtx ® -BAC 1 & 2Stabilwax ®Integra-Guard columns are available for all phaseslisted, for columns with 0.25, 0.32 or 0.53mm ID andlengths to 75 meters.42 www.restek.com
