GC COLUMNS | HIGH-PERFORMANCE RXI COLUMNSRxi®-XLB, Rxi®-35Sil MS, Rxi®-5HTRxi®-XLB (low polarity proprietary phase)• General purpose columns exhibiting extremely low bleed. Ideal for many GC/MSapplications, including pesticides, PCB congeners or (e.g.) Aroclor mixes, PAHs.• Unique selectivity.• Temperature range: 30°C to 360°C.similar phasesDB-XLB, VF-Xmstech tipIn combination with an Rxi ® -XLB column, simpleadjustments to the injection conditions can greatlyimprove sensitivity for active and high molecularweight Method 525.2 target compounds.• By eliminating contact between the sample andthe hot metal surfaces in the injection port, aDrilled Uniliner ® inlet liner prevents analytesfrom degrading in the injection port.• A pulsed injection (30psi/0.4 min.) reduces thetime the analytes spend in the injection port, andhelps to minimize breakdown.Improvements in polymer synthesis and tubing deactivation enable us to make inert,stable Rxi®-XLB columns especially well-suited for analyzing active, high molecularweight compounds with sensitive GC/MS systems, including ion trap detectors.Excellent efficiency, coupled with inertness, low bleed, and high thermal stability, makeRxi®-XLB columns ideal for analyzing semivolatile compounds in drinking water (e.g.,US EPA Method 525).Rxi®-XLB Columns (fused silica)(low polarity proprietary phase)ID df (µm) temp. limits* 15-Meter 30-Meter 60-Meter0.25mm 0.10 30 to 340/360°C 13705 137080.25 30 to 340/360°C 13720 13723 137260.50 30 to 340/360°C 137381.00 30 to 340/360°C 13750 137530.32mm 0.10 30 to 340/360°C 137090.25 30 to 340/360°C 13721 13724 137270.50 30 to 340/360°C 137391.00 30 to 340/360°C 137540.53mm 0.50 30 to 340/360°C 137401.50 30 to 320/340°C 13767 13770ID df (µm) temp. limits 10-Meter 20-Meter0.10mm 0.10 30 to 340/360°C 437010.18mm 0.18 30 to 340/360°C 43702*Maximum temperatures listed are for 15- and 30-meter lengths.
