Poly methyloctylsiloxane

Titania is being examined for use as a base material for bonded stationary phases because of its stability and its ability to separate bases under normal-phase conditions.Other researchers are investigating silica that has been surface modified with titanium oxide followed by the immobilization of poly(methyloctylsiloxane). These columns show promise for routine chromatographic analyses, but more research needs to be performed to evaluate the best manufacturing methods.

C and 29Si CP/MAS-NMR data were used to characterise the nature of gas-phase deposited y-aminopropylalkoxysilanes on heat-treated Si02.650 29Si solid-state NMR was used to characterise poly(methyloctylsiloxane) (PMOS) deposited on HPLC silica.651,652... 

Solid-state Si and CPMAS NMR have been used to characterize three different reversed-phase materials for high-performance liquid chromatography, obtained by sorption of poly(methyloctylsiloxane) onto bare silica, titanized silica and zirconized silica pores and to study the coupling of y-methacryloxypropyltrimethoxysilane on experimental nano-porous silica fillers.
