Automatic scanning of chromatograms by multi-scaling with a gamma-ray spectrometer

The location of gamma-emitting isotopes on Chromatographic thin layers is achieved, together with qualitative and quantitative analysis, by using only a gamma-ray spectrometer. This technique is applied to the determination of the Chromatographic behaviour of nanogram amounts of ⁵¹Cr, ⁵⁴Mn, ⁵⁹Fe, ⁶⁰Co, ⁶⁵Zn and ¹⁰⁹Cd thiocyanate complexes on silica gel. Separations are made of Co, Zn and Cd from Cr, Mn and Fe.
