      Increased detection sensitivity in fully off-line OPLC by bilateral band compression
      E. MINCSOVICS (OPLC-NIT Ltd, Andor Street 60, 1119 Budapest, Hungary, and Corvinus University, Faculty of Horticultural Sciences, Department of Genetics and Plant Breeding, Budapest, Hungary; emil.mincsovics@t-online.hu)

      J. Planar Chromatogr. 23, 190-192 (2010). After sample application as bands and fully off-line OPLC separation followed by drying, the separated bands were compressed bilaterally, in parallel, perpendicular to the direction of development, by use of a strong eluent and capillary driven chromatography. To introduce the eluent for band compression onto the layer a simple manual tool equipped with parallel foam strips was constructed. OPLC of a black tea leaf extract and caffeine, theophylline, and theobromine on silica gel (prewashed with acetonitrile - water 17:3) with toluene - acetic acid 3:2. Quantitative determination by densitometry at 280 nm. After band compression 20 ng/zone theophyllin and theobromine could be detected by densitometry in the xanthine standard mixture at a loading of 20 µg/10 mm. These compounds were not visible in the original, uncompressed chromatogram.
