Abstract

Multiple development is widely used for improving the resolution of planar chromatographic methods. Despite its advantageous features, multiple development cannot be generally used, because occasionally artefact spots can be observed as a consequence either of irreversible adsorption or of degradation of the analytes chromatographed. Is this work the origin and the possibilities of elimination of irreversible adsorption during multiple development are investigated and discussed. The analytical methods employed were conventional TLC and HPTLC, personal OPLC, gas chromatography, nuclear magnetic resonance spectroscopy, and mass spectrometry.
