<p>Chromatographic sheet of layer for pressurized layer chromatographic apparatus, for the development of linear chromatogram, which is characterized by sealing the sorbent layer at the edges of the sheet of layer applied conventionally with normal or fine-grained sorbent layer, and the sorbent layer is removed in one or several zones near the place of solvent admission, or one or several baffle plates or wires are arranged behind the sample application place or places, and -if necessary- it is provided with conventionally formed concentrating zone on the part from the direction of the solvent admission. The developing solvent composite does not escape at the edges of the sheet of layer in case of overpressure, and it advances with straight front. </p> |
