Fundamental study of residual silanol populations on alkylsilane-derivatized silica surfaces

Autor: J.W. de Haan, C.A.M.G. Cramers, Alex B. Scholten, Henk A. Claessens, L.J.M. van de Ven

Publikováno v: Langmuir, 12(20), 4741-4747. American Chemical Society

Two commercially available reversed phases for high-performance liquid chromatography (one dimethyl-n-octadecylsilane phase and one di-isobutyl-n-octadecylsilane phase) and the native silica substrate were subjected to deuterium exchange in a mobile

29-Silicon NMR evidence for the improved chromatographic siloxane bond stability of bulky alkylsilane ligands on a silica surface

Autor: Alex B. Scholten, Jan W. de Haan, Carel A. Cramers, Henk A. Claessens, Leo J. M. van de Ven

Publikováno v: Journal of Chromatography A. 688:25-29

A stable bond stationary phase for reversed-phase high-performance liquid chromatography, with a diisobutyl-n-octadecylsilane derivatized surface, was studied using 29Si cross-polarization magic angle spinning (CP MAS) NMR. Fumed silica surfaces (Aer

A study of the adsorption activities of silanol surface structures on a fused silica model substrate by combining29Si CP MAS NMR and inverse gas chromatographic data

Autor: Alex B. Scholten, Carel A. Cramers, Jan W. de Haan, Hans-Gerd Janssen

Publikováno v: Journal of High Resolution Chromatography, 17(2), 77-84. Wiley

Summary The possibilities of inverse gas-solid chromatography (IGC) in obtaining chromatographic data on fumed silica were examined. Aerosil A-200, a fused silica model substrate in 29Si nuclear magnetic resonance analysis, was trimethylsilylated to
