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.

Chromatographic sheet and/or a system of chromatographic sheets for

The invention relates to a new polyacrylamide adhesive suitable for the fixing of fine-particle sorbent layers based on organic and/or inorganic compounds, used in overpressured one- and multilayer chromatographic procedures. The said adhesive is prepared by polymerizing the aqueous solutions of acrylamide and N,N'-methylene-bis-acrylamide in the presence of a catalyst pair at from 21.degree. to 30.degree. C., pulpifying the precipitate thus obtained and repeating the precipitation and the pulpification more times.
