PerkinElmer Brownlee SPP 2.7 µm Phenyl-Hexyl 2.1 X 20 mm - N9308481

Alternative selectivity to alkyl bonded phases, recommended for aromatic groups. Compatible with highly aqueous mobile phases to facilitate the retention and separation of polar compounds. Base-deactivated for good peak shapes when separating basic compounds. Hexyl spacer provides optimal flexibility for phenyl ring to facilitate p-p interactions with solutes. Its features and benefits include - Solid inner core, porous silica outer shell, shorter diffusion path; Very high efficiencies at moderate back pressures, Nearly twice the efficiency of 3-µm particle columns, As robust as columns packed with 5-µm particles because columns use 2-µm frits, Can exceed performance of sub-2-µm particle size columns on most standard 6000 psi HPLC systems, Can be used on UHPLC system at pressures up to 9000 psi Longer columns can be used for very high column efficiencies on UHPLC systems and Optimization kits available for Series 200 and Flexar LC systems to increase application efficiencies.
