Extract
Geological samples prepared for analysis by X-ray fluorescence (XRF) are particularly prone to intrasample and intersample phase variations creating significant inhomogeneity and variations in matrix effects. These features may “best be eliminated or diminished by fusion of the sample with, a suitable flux (1,2). Presentation to the X-ray spectrometer may be as a briquet of the comminuted fusion head (1,3,4,5) or as a molded glass disc or wafer (l,2,5,6). Because of the stability of glass discs and the necessity to eliminate possible contamination during grinding and making briquets, molded glass discs appear to be the best and easiest means of presentation.
