Popis:	A novel method had been developed to prepare ADS packings. Different alkyl-chains were bound onto Develosil60-5μ silica (particle size dp = 5 μm, s = 400–450m2/g) with γ-glycidoxypropy-ltrimethoxysilane as coupling agent and hydrophilic diol phase precursor. Characterization of the packings was carried out with elemental analysis, X-Ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared (FT-IR), solid-state 13C, and 29Si CP-MAS NMR. Chromatographic tests confirm the essence of the packings and RAS behavior.
