Restek Raptor™ C18 90 Å HPLC Columns
High-Efficiency Reversed-Phase HPLC Columns for Routine and Advanced LC Applications
The Restek Raptor™ C18 90 Å HPLC column series combines a high-purity C18 (octadecylsilane) stationary phase with Restek's proven 2.7 µm superficially porous (core-shell) particle technology to deliver exceptional chromatographic efficiency, outstanding peak symmetry, and robust reproducibility. Designed for both conventional HPLC and UHPLC systems, the Raptor C18 provides a versatile solution for routine quality control, pharmaceutical analysis, environmental testing, food safety, and LC-MS/MS applications.
As the most widely used reversed-phase chemistry, the Raptor C18 offers balanced hydrophobic retention and excellent selectivity for a broad range of acidic, basic, neutral, and moderately hydrophobic compounds. The combination of a fully bonded, endcapped stationary phase and advanced core-shell particles enables high-resolution separations, shorter analysis times, and lower operating backpressure compared to fully porous sub-2 µm columns.
Whether developing new analytical methods or transferring established USP methods, the Restek Raptor C18 90 Å delivers reliable performance and excellent reproducibility across a wide variety of chromatographic applications.
Key Benefits
- Universal C18 reversed-phase stationary phase suitable for the majority of HPLC and UHPLC applications.
- High chromatographic efficiency using 2.7 µm superficially porous (core-shell) silica particles.
- Excellent retention and peak shape for acidic, basic, neutral, and hydrophobic compounds.
- Fully bonded and endcapped stationary phase minimizes secondary interactions and improves peak symmetry.
- Fast mass transfer enables shorter run times without sacrificing resolution.
- Lower operating backpressure compared to fully porous sub-2 µm particles.
- Excellent reproducibility for routine quality control and validated analytical methods.
- Fully compatible with HPLC, UHPLC, UV, PDA, fluorescence, and LC-MS/MS detection systems.
- Robust performance with aqueous and organic mobile phases.
