Title
(EN) CHROMATOGRAPHY AND OTHER ADSORPTIONS USING MODIFIED CARBON-CLAD METAL OXIDE PARTICLES
(FR) CHROMATOGRAPHIE ET AUTRES PROCEDES D'ADSORPTION FAISANT INTERVENIR DES PARTICULES D'OXYDE METALLIQUE ENROBE DE CARBONE
Abstract
(EN)
Separation devices and systems are described which have a stationary phase and a mobile phase, wherein the stationary phase contains carbon-clad zirconium dioxide particles having attached at least one organic group. The stationary phase which is used in the present invention has the ability to dial in the selectivity by attaching the proper organic groups onto the carbon-clad zirconium dioxide particles in order to achieve the desired separation. Various separation processes are described such as chromatography, electrophoresis, magnetic separations, membrane separations, and the like. The processes to accomplish these types of separations are also described.
(FR)
Cette invention a trait à des dispositifs et à des systèmes de séparation comportant deux phases, stationnaire et mobile, la phase stationnaire contenant des particules de dioxyde de zirconium à enrobage de carbone auxquelles est attaché au moins un groupe organique. La phase stationnaire utilisée pour cette invention est capable de sélectivité en rattachant les groupes organiques appropriés sur les particules de dioxyde de zirconium à enrobage de carbone afin de permettre la séparation souhaitée. L'invention porte également sur divers procédés de séparation, notamment sur la chromatographie, l'électrophorèse, les séparations magnétiques, les séparations par membrane et analogue. Les procédés de mise en oeuvre de ces différents modes de séparation sont également décrits dans l'invention.
