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.
