Preparation of pre-coated rp-rotors and universal chromatorotors, chromatographic separation devices and methods for centrifugal preparative chromatography

摘要: Reversed phase solid silica gel sorbent layers which can adhere with appropriate binders to a surface were developed. Pre— coated RP-rotors of different thickness used Thes pre-coated be for Centrifugal Preparative Thin-layer Chromatography (CPTLC) using any device Chromatography, like Chromatotron® or Cyclograph. Organic compounds including very polar ones separated and /or purified in preparative scale from mixtures by these RP-rotors, solvent systems. Also described is new chromatographic separating (hereinafter Chromato Rotor) method separation constituents natural products mixture organic centrifugal instrument element contains binder free layer packed loaded between tvvo supporting rotors retained moving outside porous filter. Only eluants pass through. ChromatoRotors sorbentswith dimensions capacity prepared separation. Virtually classes due the unlimited combination sorbents mobile phases, but not limited aqueous-based solvents. These plates also CPTLC Cyclograph® instruments.
