Abstract
The present invention relates to a chromatographic sheet and/or a system of chromatographic sheets for overpressured multilayer chromatography. One or more chromatographic sheets with sorbent layer are optionally sealed at their edges preferably by impregnation or coating with a polymer film and holed at the solvent inlet in adequate size and shape and they are optionally included in a system in single or multiple layers with or without a conventional chromatographic sheet sealed at its edges.
Claims13
An overpressured multilayer chromatographic system comprising at least two chromatographic sheets superposed relative to one another, each of said chromatographic sheets including a sorbent layer on one side, said respective sorbent layers being sealed at at least one of their respective edges, at least one of said chromatographic sheets having a hole formed therethrough of adequate size and shape for eluent inlet and an eluent leading channel formed proximate to said hole to provide a linear eluent front, and the lowermost of the superposed chromatographic sheets being without a hole.
