Qualitative and Quantitative X-Ray Fluorescence Analysis

3.1 EVALUATION OF X-RAY FLUORESCENCE SPECTRA

After the acquisition of an XRF spectra, the spectrum itself is just a data set and not yet a result. It is an iterative process of spectra correction and evaluation that leads to providing the solution to the analytical task from a spectrum, which can be focused on obtaining information on the elements present in the target sample (qualitative analysis) and/or on the quantification of the amount of the elements present in the target sample (quantitative analysis). In Figure 3.1, a brief summary of the different steps involved in spectra evaluation is shown.
