Allgemeine Beschreibung

Ascentis® Express 2.0 μm F5 is a high-speed, UHPLC column based on a Fused-Core® particle design. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.4 μm thick porous shell and the small overall particle size of 2 μm. The bonded, endcapped, dimethylpentafluorophenylpropyl stationary phase of Ascentis® Express 2.0 μm F5 provides a stable, reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines. In addition to forming pi-pi and mildly steric interactions, F5 phases also retain compounds by polar interactions. Having polar and non-polar character, F5 phases can show dual-mode retention behavior, sometimes producing a “U-shaped” retention as a function of acetonitrile content of the mobile phase, with retention increasing at both low and high concentrations of ACN (reversed-phase and HILIC retention modes). Ascentis® Express 2.0 μm F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.

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.
