Abstract

The analytical performance of different X-ray emission elemental analysis techniques is compared for two applications. Synchrotron radiation X-ray fluorescence [SRXRF] with tunable monochromated excitation gives a lower detection limit than PIXE for dried biological samples. The superiority of SRXRF is most pronounced for elements with Z>30. Experimental indications are given that SRXRF can be more sensitive than electron-probe X-ray microanalysis for small-volume or individual-particle analysis of environmental samples for elements with Z>40.
