Raptor FluoroPhenyl, 1.8 µm, 50 x 3.0 mm HPLC Column
Raptor FluoroPhenyl, 1.8 µm, 50 x 3.0 mm HPLC Column
Overview
- Retains hydrophobic, polar, and aromatic compounds.
- Has orthogonal selectivity to a C18.
- Exceptionally reproducible—predictable performance from every column.
- Part of Restek’s Raptor LC column line featuring 1.8, 2.7, and 5 µm SPP core-shell silica.
- Switch to a Raptor FluoroPhenyl LC column when you need more retention and selectivity for basic and hydrophilic compounds than you can achieve on a C18.

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 with existing HPLC and UHPLC instrumentation.
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.
