Abstract
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.
