Determination of radionuclide species by on-line radiochromatography using high resolution gamma ray spectroscopy
A high resolution Ge(Li) ..gamma..-ray spectroscopy detector for the on-line multielement monitoring of liquid chromatographic column effluents containing mixtures of ..gamma..-mixing radionuclides is described. Two spectra are collected simultaneously during the experiment - one to determine the individual ..gamma..-emitting components and one to determine the total radionuclide activities. The technique was successfully applied to the separation and determination of /sup 65/Ni(II), /sup 56/Mn(II), /sup 60/Co(II), /sup 64/Cu(II) by anion-exchange; acetylacetonate (acac) of /sup 51/Cr(III), /sup 60/Co(II), /sup 64/Cu(II), and /sup 56/Mn(II); and diethyldithiocarbamate, oxinate, and acetylacetonate of /sup 64/Cu(II) by silica gel adsorption chromatography. Advantages of this method over a uv detection method are discussed. Detection limits of /sup 51/Cr, /sup 69m/Zn, /sup 64/Cu, /sup 56/Mn, /sup 65/Ni, and /sup 60/Co separated on Dowex-1X8 were found to be 82, 11, 37, 25, 234, 35 nCi, respectively, at a flow rate of 1.0ml/min and for a cell volume of 75 ..mu..l. Detection limits of metal complexes separated on silica gel were found to be 2.85 x 10/sup -4/, 7.6 x 10/sup -5/, 8.3 x 10/sup -6/, 1.3 x 10/sup -5/ mmoles of Cr(acac)/sub 3/, Co(acac)/sub 3/, Cu(acac)/sub 2/, and Mn(acac)/sub 3/, respectively, at a flow rate of 2.0 ml/min and for a cell volume of 116 ..mu..l.
