A planar centrifugal chromatography device includes a chamber (2), and a rotor (3) arranged therein, driven by a motor (12) and serving as a separating element. The rotor has a supporting plate (15) with an adsorbing medium (4) provided thereon. A collecting device (5) is arranged near the outer edge of the rotor, but within the chamber. The characteristics of the invention include the collecting device (5) and the rotor (3) being mounted on a common shaft (10) and each individual point of a wall of the collecting device (5) being farther away from the axis of rotation (14) than the point of the adsorbing medium (4) which is farthest from the axis of rotation (14), and include the distances of individual points on the wall of the collecting device (5), measured from the axis of rotation (14), varying. At each point on the collecting device which is farther from the axis than two points which are adjacent to it, there is arranged an output opening (6) which is connected by a discharge channel (7) to a hollow part of the shaft (10) of the rotor (3), and wherein a stationary discharge element (8), for example a pump, is connected to the shaft (10).

The invention relates to an apparatus for overpressured thin-layer chromatographic technique, comprising at least one carrier plate arranged adjacent a closed space, a sorbent layer arranged on the surface of said carrier plate, means for covering the surface of said sorbent layer under influence of overpressure generated in said closed space, a first inlet for admitting solvent to said sorbent layer, a second inlet for admitting overpressurizing medium into said closed space, a heating unit for altering temperature of said sorbent layer and a temperature control unit for energizing said heating unit. The apparatus according to the invention ensures improved efficiency of the chromatographic developments carried out under overpressure. By means of the apparatus chromatograms can be obtained with increasing speed of separation.

Apparatus for overpressured thin-layer chromatographic technique

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.

The invention relates to a new method for increasing the biological value of manures, dung-waters, organic wastes and/or soils rich in lysine. According to the invention manure, dung-water, an organic waste and/or soil rich in lysine, either of natural composition or supplemented with lysine, a lysine source and/or one or more agricultural chemical(s), is treated with at least 0.01 mole of formaldehyde or an equivalent amount of a formaldehyde source, calculated for one mole of free or bound lysine present. The treatment according to the invention results in a significant increase of plant growth and crop yield.

Method for increasing the biological value of manures, dung-waters,

A linear overpressured thin layer chromatographic apparatus comprises a base plate 3 supporting a sorbent layer 1 over which a membrane 4 is filled. The membrane 4 is externally pressurized by a fluid medium 10. A transparent cover plate 5 is fitted over the membrane 4, and there are sealed inlets 6, 7 passing through the cover plate 5 for the introduction of the mobile phase and the samples.
