Descrizione generale
Ascentis® Express 2μm Phenyl-Hexyl UHPLC columns are based on a 90 Å Fused-Core® particle design.The Fused-Core particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.4-micron thick porous shell and the small overall particle size of 2-microns. The bonded, endcapped, dimethylphenylhexyl stationary phase of Ascentis Express 2μm Phenyl-Hexyl provides a stable, reversed phase packing with enhanced p-p and mild steric interactions due to the relatively long-chain hexyl linkage to the base silica. Ascentis Express 2μm Phenyl-Hexyl can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.

The recent introduction of new stationary phases for liquid chromatography based on superficially porous particles, called core-shell or fused-core, dramatically improved the separation performances through very high efficiency, due mainly to reduced eddy diffusion. However, few studies have evaluated the

On-line sample pretreatment (clean-up and analyte preconcentration) is for the first time coupled to sequential injection chromatography. The approach combines anion-exchange solid-phase extraction and the highly effective pentafluorophenylpropyl (F5) fused-core particle column for separation of eight sulfonamide antibiotics with similar
