Sowden, Miles Uranium hexafluoride Quantitative mass spectrometric UCTD Dissertation (MSc)--University of Pretoria, 1993. A method has been developed that uses uranium hexafluoride as the internal standard to quantitatively determine trace impurities in the uranium hexafluoride using relative response factors. A computer program was written to control the mass spectrometer and determine the concentrations of target impurities present. Overlapping spectra are deconvoluted using the Gauss-Seidel iterative method. The composition of the sample is determined by comparing the peak height ratios of the target impurities to the internal standard. Measurement parameters are easily modified using the menu driven program. A flexible database allows the list of target impurities to be extended to accommodate any changes in analytical requirements. The method has been adapted for automatic on-line measurements. The technique was evaluated by analysing a number of carefully prepared standards. Nine target impurities were studied which ranged in concentration from parts per million to percentages. An overall precision of fifteen percent was obtained. gm2013 Chemistry unrestricted 2013-12-10T08:41:49Z 2013-12-10T08:41:49Z 1993-10-05 1993 Dissertation Sowden, M. 1993, Quantitative mass spectrometric determination of trace impurities in uranium hexafluoride using relative response factors, MSc dissertation, University of Pretoria, Pretoria, viewed yymmdd <http://hdl.handle.net/2263/32781> E13/9/1106/gm http://hdl.handle.net/2263/32781 en © 1993 University of Pretoria.
