Analysis of Cd, Sn, Sb, Cs, Ba,La, Ce and Nd in rocks and soils–improved detection limits using K-series lines

IntroductionX-ray fluorescence spectrometry is used extensively for geochemical analysis. Simple sample preparation, accuracy, precision and good to excellent detection limits across large parts of the periodic table are the principal reasons for this choice. Detection limits for typical medium-power wavelength-dispersive spectrometers (WDXRF) configured for geological applications are illustrated in Figure 1.
