      Densitometric acquisition of concentration profiles in planar chromatography and its possible shortcomings, Part 1

      Acta Chromatographica 14, 5-15 (2004). Investigation of lateral interactions of 4-phenylbutyric acid in mild planar chromatographic systems comprising low-activity stationary phases, such as microcrystalline cellulose or chromatography paper, and low-polarity decalin as mobile phase. Acquisition of densitograms of the bands of interest was carried out in order to judge the presence or absence of lateral interactions of the analyte in the chromatographic system by comparison of the shape of the concentration profile. Discussion of the observation that the concentration profile of 4-phenylbutyric acid on cellulose powder could be easily measured on a freshly developed chromatogram only after drying whereas on chromatography paper developed at room temperature it was hardly detectable, and became fully shaped only two days later. Presentation of a tentative explanation on this phenomenon.
