Accucore Phenyl-Hexyl Columns

Thermo Scientific Accucore PhenylHexyl columns offer unique selectivity for aromatic and moderately polar analytes. Based on Core Enhanced Technology, Accucore columns provide fast, high-resolution separations – without the elevated backpressures required by sub-2µm particles. Mixed-mode Selectivity for Aromatic and Moderately Polar Analytes Enhanced Pi-pi Interactions with Aromatics Moderate Hydrophobicity The C6 chain in Accucore Phenyl-Hexyl phase exhibits classical RP retention and selectivity, while the phenyl ring can add special selectivity by interacting with polar groups within the solutes. This results in a mixed-mode separation mechanism. Phenyl-Hexyl phase should be selected for complex samples where some peaks are well resolved on a conventional alkyl phases, but are not well resolved on a conventional phenyl phase. While other peaks are well resolved on a phenyl phase, but not well resolved on a conventional alkyl phase.   Description Particle Size Length (mm) 2.1mm ID 3.0mm ID 4.6mm ID             Analytical Columns Accucore Phenyl-Hexyl 2.6μm 30 17926-032130 17926-033030 17926-034630 50 17926-052130 17926-053030 17926-054630 100 17926-102130 17926-103030 17926-104630 150 17926-152130 17926-153030 17926-154630             Guard Columns Accucore Phenyl-Hexyl 2.6μm 10 17926-012105 17926-013005 17926-014005 UNIGUARD Drop-In Guard Cartridge Holder 852-00 852-00 850-00 Standard Replacement Tip 850-RT 850-RT 850-RT
