Raptor FluoroPhenyl LC Columns Material: (USP L43) • Capable of both reversed-phase and HILIC separations. • Ideal for increasing sensitivity and selectivity in LC-MS analyses. • Offers increased retention for charged bases. • Part of Restek’s Raptor LC column line featuring 2.7 and 5 ?m 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 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.
