Despite its advantages, EDX also has several limitations:
Detection limits: EDX may not detect elements present in very low concentrations, which can be a limitation when analyzing highly dilute catalytic species. Spatial resolution: The spatial resolution of EDX is limited by the interaction volume of the X-rays and electrons in the sample, which may affect the accuracy of elemental mapping at nanoscale dimensions. Sample preparation: Proper sample preparation is crucial to avoid artifacts and ensure accurate results. Overlapping peaks: Elements with similar atomic numbers may have overlapping peaks, complicating the interpretation of the spectrum.
