Analysis of Mineral Samples X-Ray Spectrometrically Using Ion Exchange Separation Techniques
MetadataShow full item record
An ion exchange separation procedure has been devised for the determination of trace and minor constituents of samples of geological or biological origin using an energy dispersive, secondary source, x-ray spectrometer. Elements which interfere in the analysis are separated using ion exchange chromatography and analysed separately. This allows for the quantitative determination of elements which are either completely masked or prohibitively interfered with by other constituents in the spectrum of the original sample. The procedure in the text describes the separation and analysis of eighteen minor and trace elemental constituents common to geological samples. Using energy dispersive, secondary source x-ray spectrometry detection in the nanogram region for these elements is possible.
