ABSTRACT:
A novel plate system for thin layer chromatography comprises a supporting plate coated over about 50-90% of its area with an adsorbent layer, the uncoated surface comprising at least one strip of uniform width along an end of the supporting plate. Two such plates grafted and clamped in a lap-joint so that the edges of the adsorbent layers are in intimate contact provide an assembly on which a chromatogram developed on the first plate can be transferred in whole or in part onto the second plate. The assembly and technique are particularly useful for preparative thin layer chromatography.
