General description

Ascentis® Express 90 Å Biphenyl is a high-speed, high-performance liquid chromatography column based on a superficially porous Fused-Core® particle design. The 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 μm thick porous shell and the small overall particle size of 2 μm. The bonded, densely endcapped, dimethyl-biphenyl stationary phase provides a stable, reversed phase packing with enhanced pi-pi and mild steric interactions due to the two sequential phenyl groups bonded to the base silica. The 90 Å Biphenyl can be used for basic, acidic, or neutral compounds with alternate selectivity from C18 and is especially useful for separating peaks that elute early on C18 and other phenyl phases.

Application

UHPLC/MS Analysis of Pain Management Opiates
UHPLC/MS Analysis of SAMHSA 5 Panel on Ascentis® Express Biphenyl, 2 μm

Analysis Note

Target analytes include electron-poor molecules, aromatic or unsaturated compounds (ketones, nitriles, alkenes).

HPLC pour petites molécules

Les petites molécules sont des ions et des composés dont le poids moléculaire est généralement inférieur à 900 daltons. Ces composés peuvent être efficacement séparés et analysés par HPLC, UHPLC et LC-MS en utilisant principalement des particules de silice ou des phases stationnaires monolithiques avec une large gamme de chimies de colonnes (modifications).

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).
