| Abstract: | The preparation of a very thin chromatographically active Al203-layer on small aluminium plates or wires by a new anodic oxidation method is described. The excellent suitability of this Al2O3-layer for application to separations are demonstrated by the examples of “thin-film Chromatographic” separations of a mixture of dye stuffs, some metal dithizonates and metabolites of the pesticide Endosulfan in the ng and pg range. |
