2 People rely on you for fast, accurate data. Rely on Rxi columns to deliver it. Your instrument needs to run, it needs to run now, and it needs to give you the right results the first time. Ground-breaking Rxi 3-in-1 technology unifies outstanding inertness, low bleed, and high reproducibility into a single high-performance column line that gives you the foundational low-level accuracy you need. Outstanding Inertness Our 3-in-1 technology produces such inert columns we name them Restek extreme Inertness (Rxi ). Extreme inertness improves signal-to-noise ratios and heightens sensitivity to lower detection limits while generating consistent peak shapes and retention times. Rxi inertness gives you predictable retention times, good peak shapes, and easy, accurate integration. 5 ng, 2.2 min A: Pyridine on non-rxi column 5 ng, 2.39 min B: Pyridine on Rxi column 2.5 ng, 2.8 min 1 ng, 2.32 min 1 ng, 2.40 min 0.5 ng, 2.41 min Time (min) Time (min)

3 Low Bleed Rxi columns are more stable, so even at higher temperatures, they generate less bleed and reduce background to further improve signal-to-noise ratios, enhance sensitivity, and lower detection limits. Improve sensitivity and accuracy at trace levels with low-bleed Rxi columns Reference Peak 1 ng tridecane 350 C Column A pa 330 C Column B Column C Column D Column E Column F Rxi -5ms Time (min) GC_EV00822 Comparison of 30 m x 0.25 mm ID, 0.25 µm 5%-diphenyl columns at 330 C through 350 C; hydrogen carrier gas; flame ionization detection. High Reproducibility Unmatched manufacturing precision and stringent quality control mean that every Rxi column performs the same way as the column it replaces, every time. We exceed industry standards for efficiency, retention, bleed, and inertness. Choose Rxi columns to ensure column-to-column and lot-to-lot reproducibility.

4 Optimized Efficiency and Selectivity Rxi columns also feature the efficiency to generate sharp, narrow peaks, so target analytes are still separated at high temperatures. When coupled with the right selectivity, this efficiency lets you perform analyses much faster without losing resolution. Higher efficiency (i.e., more plates per meter) means better separations on an Rxi column. Non-Restek N=3,900 plates/meter Restek Rxi Technology N=4,270 plates/meter N=4,270 plates/meter The Rxi column line spans the polarity range, so you can easily select the perfect selectivity to help you run faster and produce unbeatable results. Rxi columns are available in a wide range of polarities.

7 SPP speed. USLC Resolution. A New Species of Column Restek is excited to announce the evolution of superficially porous particles with the introduction of Raptor LC columns and guards. Superficially porous particles (commonly referred to as SPP or core-shell particles) changed the world of LC by dramatically boosting column efficiency and reducing analysis times, but they were only the beginning. With Raptor LC columns, Restek chemists have combined the speed of SPP with the resolution of highly selective USLC technology. This new species of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. Higher efficiency for drastically faster analysis times. Better selectivity for substantially improved resolution. Increased sample throughput with existing HPLC instrumentation. Coming soon: 5 µm particles and a full suite of phases! Put Raptor LC columns and guards to the test on your most challenging workflows! Learn more and order today at Dissecting the Raptor LC Column Larger 2 μm Frit Prevents clogging better than commonly used 0.5 μm frits; boosts column lifetime and helps maintain optimal pressures. Rugged Label Clearly identifies both flow direction and column; resists solvents and tearing to last as long as your column does. Proprietary Column- Packing Technique Provides greater pressure stability (8,700+ psi / 600+ bar); achieves higher linear velocities without sacrificing efficiency or lifetime. Raptor SPP Particles Robust 2.7 μm Particles Let you run high-speed analyses without UHPLC. Narrow Silica Distribution Ensures high efficiency and consistent flows. Updated Bonding and QC Guarantee retention time stability, run to run and column to column.
