Intensity correction of WD‐XRF spectra from 2θ to energy

Generally, the energy‐dispersive X‐ray fluorescence spectra are plotted as an equi‐energy interval with the constant energy resolution. On the other hand, the wavelength‐dispersive X‐ray fluorescence spectra are usually measured with an equi‐angle interval supposed the constant angular resolution. When the wavelength axis of wavelength‐dispersive X‐ray fluorescence spectra is converted into energy, the intensity should be also corrected. This intensity correction is important even for a narrow scan range such as Pb Lα and Lβ peaks. The intensity ordering is Lβ > Lα for 2θ plot, but it becomes Lα > Lβ for energy plot. The detailed conversion equations for abscissa and ordinate axes are presented. Copyright © 2012 John Wiley & Sons, Ltd.
