    Notes: Summary A thin-layer chromatographic method for the separation and identification of hitherto unknown disubstituted triphenodioxazines in submicrogram amounts has been developed using silica gel plates. The solvent systems used are acetone-petroleum ether (60∶40), benzene-petroleum ether (80∶20) and acetone-petroleum ether (50∶50). The compounds are detected by spraying the plates with 0.05 mol dm−3 sulphuric acid.

    Notes: An X-ray fluorescence method for the measurement of film and coating thickness has been described for use in situations where standard foils of the same material are not available for comparison. The method is based on the measurement of combined mass absorption coefficient of the coating element at the excitation and at the fluorescent energies using thin samples of a compound in which the coating element is present and then calculating the coating thickness using the fluorescence equation. The paper describes the theoretical approach and presents the result of the measurement of certain film and coating thicknesses which support the theoretical considerations.
