Description générale

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.

Research shows that immunoassay techniques are not the best choice for the estimation of vitamin D in human blood samples. The main reasons are that some immunoassays are not able to distinguish between 25-OHD3 and 25-OHD2 vitamin D metabolites. Furthermore

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).

Les petites molécules sont des ions ou des composés d'une masse moléculaire généralement inférieure à 900 daltons. Ces molécules peuvent être séparées efficacement et analysées par HPLC, UHPLC et LC-MS en utilisant essentiellement des particules de silice ou des phases stationnaires monolithiques présentant un large éventail de chimies de colonnes (modifications) différentes.
