OPEN CHROMATOGRAPHIC CAPILLARY COLUMN WITH STRUCTURED SORBENT Russian patent published in 2008 - IPC G01N30/56 

FIELD: chemistry.

SUBSTANCE: in the open chromatographic capillary column consisting of capillary on internal surface of which evenly longwise of column the bed of keeping substance is put which is executed in the form of an indissoluble film with a regular cellular structure with effective diameter over the range 2-30 nanometers, and the deviation from effective diameter is subordinated to the law of Gauss with a dispersion no more than 5 nanometers. Thus keeping substance consists of oxides on the basis of silicon, aluminium, the titan, or siloxane copolymer, contains either carbon, or polymer on the basis of divinyl benzene, copolymers of divinyl benzene and styrene, vinylpyridine and divinyl benzene, styrene and, ethylene glycol dimethacrylate, and a capillary material on which the structured bed is put, is the quartz, glass, metal.

EFFECT: achievement of specific efficiency to the value of 2100-2500 theor plates on metre and possibilities to work at the raised values of a gas stream of the carrying agent without an essential decline of efficiency; separation process acceleration without a significant decline of dividing properties of a column; time decreasing of the analysis at a problem solving.
