  1. Ink analysis from typed script of electronic typewriters by high performance thin layer chromatography.

    Article - En anglais

    The analysis of ink from the typed script of seven electronic typewriters is carried out by high performance thin layer chromatography.

    The resultant Rf values and in situ visible spectrum of each resolved band of all the chromatograms indicate that the same chemical composition is being used in six typewriter ribbon inks, but that the seventh one is completely different.

    The method is, however, a destructive one, but extremely sensitive and may be employed in the routine analysis.
