Raptor LC columns have been providing higher efficiencies, faster analyses, and rock-solid reliability to HPLC users for several years. And they have just evolved again. Restek has brought the benefits of Raptor columns to those who have made the leap to UHPLC instruments, yet are still looking to boost their efficiencies further. Already sold with 2.7 and 5 urn superficially porous particles (SPP), Raptor columns are now available with 1.8 urn particles specifically for use with UHPLC. Choose from four distinctive Restek phase chemistries: Biphenyl, ARC-18, C18, and FluoroPhenyl.
