Abstract: The unique hybrid phase in Raptor Polar X columns balances HILIC and ion exchange retention modes, making it ideal for analyzing a wide range of polar compounds, especially when coupled with mass spectrometry.

Separate a Wide Variety of Polar Analytes with New Raptor Polar X Columns

Analyzing polar compounds using liquid chromatography has historically been a challenge. Poor retention and peak shape, complex mobile phases that may not be MS-friendly, long equilibration times, low sensitivity, and sample derivatization are all complications that reduce lab efficiency and productivity. However, new Raptor Polar X columns reliably retain and efficiently separate a broad range of polar analytes using a unique stationary phase that balances two retention mechanisms: HILIC and ion exchange. This hybrid phase is ideal for analyzing acidic, basic, and neutral polar compounds without time-consuming derivatization or complex ion pairing, and it is especially compatible with mass spectrometry. Easy changes to mobile phase conditions allow analysts to switch between modes and selectively tune retention for the compounds of interest without needing long equilibration times. Simplify the analysis of polar compounds with the resolving power of Raptor Polar X columns from Restek.

About Raptor SPP LC Columns:
Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation.

Simplify the Switch to HILIC with Raptor HILIC-Si Columns

Restek is bringing the speed and reliability of Raptor LC columns into the HILIC realm with the addition of the Raptor HILIC-Si column. HILIC is an increasingly popular alternative to reversed-phase LC for challenging polar analytes because it provides better retention of water-soluble compounds that are separated by polar differences. The Raptor HILIC-Si column simplifies the switch to HILIC because it delivers rugged Raptor performance, provides SPP column speed for faster analyses than traditional FPP silica columns, retains polar compounds without ion-pairing reagents, and is fully reliable, efficient, and selective with LC-MS compatible mobile phases.

New Raptor™ FluoroPhenyl Phase: the Power of HILIC and RP Modes in One LC Column

Raptor_Fluorophenyl_Skroup_CRM-(2)Restek has now extended the speed and reliability of Raptor™ column technology into the HILIC realm with the addition of Raptor™ FluoroPhenyl columns. Restek’s Raptor™ FluoroPhenyl phase offers chromatographers the ability to run in reversed-phase or HILIC mode for a variety of compounds. The Restek® Raptor™ FluoroPhenyl column is also amenable to LC-MS because it is extremely reliable and efficient with acidic mobile phases.
