Accucore PFP Columns

Thermo Scientific Accucore PFP columns offer alternative selectivity to C18, particularly for halogenated analytes. Based on Core Enhanced Technology, Accucore columns provide fast, high-resolution separations – without the elevated backpressures required by sub-2µm particles. Alternative Selectivity to C18 Extra Retention for Halogenated Species Unique Selectivity for Non-halogenated Polar Compounds Introduction of fluorine groups into the Accucore PFP (pentafluorophenyl) stationary phase causes significant changes in solute-stationary phase interactions. This can lead to extra retention and selectivity for positional isomers of halogenated compounds. PFP Columns are also well suited to the selective analysis of non-halogenated compounds, in particular polar compounds containing hydroxyl, carboxyl, nitro, or other polar groups. High selectivity is often most apparent when the functional groups are located on an aromatic or other rigid ring system.   Description Particle Size Length (mm) 2.1mm ID 3.0mm ID 4.6mm ID             Analytical Columns Accucore PFP 2.6μm 30 17426-032130 17426-033030 17426-034630 50 17426-052130 17426-053030 17426-054630 100 17426-102130 17426-103030 17426-104630 150 17426-152130 17426-153030 17426-154630             Guard Columns Accucore PFP 2.6μm 10 17426-012105 17426-013005 17426-014005 UNIGUARD Drop-In Guard Cartridge Holder 852-00 852-00 850-00 Standard Replacement Tip 850-RT 850-RT 850-RT
