Allgemeine Beschreibung

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

Small Molecule HPLC

Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).

HPLC niedermolekularer Verbindungen

Niedermolekulare Verbindungen, sogannte Small Molecules, sind neutrale und ionische Verbindungen mit einem Molekulargewicht, das üblicherweise unterhalb von 900 Dalton liegt. Diese Verbindungen können durch HPLC, UHPLC und LC-MS vornehmlich unter Verwendung von Kieselgelpartikeln oder monolithischen stationären Phasen mit einem breiten Spektrum von „Säulenchemien“ (Modifikationen) effektiv getrennt und analysiert werden.
