Phenomenex Catalog International 2009 - (Page 56) Zebron GC Columns ™ ZB-5HT Inferno™ • First non-metal columns stable to 430 °C • Robust column for high temperature analysis, such as biodiesel, long-chain hydrocarbons, polymers, and high molecular weight compounds • Longer lifetime with rugged high temperature, polyimide coated, fused silica tubing • Low activity, provides good peak shape for acidic and basic samples • Individually tested for low bleed, MS certified • Temperature Limits: -60 to 400/430 °C (Isothermal/TPGC)* Column Profile Low Polarity Bleed Temperature Limits Stability High 8 Applications • • • • • High Boiling Petroleum Products Triglycerides Simulated Distillation Methods Diesel Fuel Long-chained Hydrocarbons • • • • Motor Oils Polymers/Plastics Surfactants High Molecular Weight Waxes Alternative to Any 5 %-Phenyl-95 % Dimethylpolysiloxane High Temperature Phase: ZEBRON GC COLUMNS | GC COLUMNS & ACCESSORIES • DB-5ht • VF-5ht • HT-5 • Stx-5HT • XTI-5HT Bleed Test 25 23 21 19 17 Zebron™ ZB-5HT Inferno™ Agilent® J&W® DB-5ht Free and Total Glycerin in B-100 Biodiesel Methyl Esters: ASTM Method D 6584 Improved Glycerol Resolution High Sensitivity for Triolein Ultra Low Bleed at 380 °C 3 pA 15 13 11 9 7 5 0 5 10 15 20 25 30 35 min 6 2 4 5 7 8 9 10 Conditions for all columns: Dimensions: 30 meter x 0.25 mm x 0.10 μm Injection: Null Injection @ 250 °C Carrier Gas: Hydrogen @ 11 psi (Constant Pressure) Oven Program: 120 °C for 3 min to 320 °C @ 30 °C/min (hold 5 min) to 340 °C @ 30 °C/min (hold 5 min) to 360 °C @ 30 °C/min (hold 5 min) to 380 °C @ 30 °C/min (hold 5 min) to 400 °C @ 30 °C/min (hold 5 min) Detector: FID @ 405 °C The shaded area depicts the bleed criteria for MS certified columns on a MS detector. MS bleed certification values are typically read at 320 ºC. This demonstrates the low bleed capabilities of the ZB-5HT. It meets MS certification limits even at 360 ºC! 1 10 20 min Column: Dimensions: Part No.: Injection: Carrier Gas: Oven Program: All columns used for above tests were new/never used, prior to this testing and purchased either directly from the original manufacturer or through an authorized distributor. All testing was carefully controlled to ensure conditions were similar for all columns involved. The comparative data may not be representative of every application.
