    摘要: Method for preparing samples for spectrometric analysis by X-ray fluorescence, includes the steps of:
    - selecting a quantity of analyte to be analyzed;
    - adding to the analyte a solution comprising both a binder and an internal standard, wherein the addition is executed in a single step of adding said solution, the method does not comprise a step of for further grinding;
    - mixing the composition;
    - drying the composition, using a specific solvent;
    - transferring the dried residue inside the container for pressing;
    - pressing the dried residue to form a tablet;
    - extracting the tablet obtained from the container;
    - subjecting the tablet to spectrometric analysis using X-ray fluorescence,
    - correcting the analyte signal using a correction factor calculated on the basis of the internal standard signal.
