Heavy metal analysis

measures the fluorescence emitted by atoms in a sample excited by a light source.
X-ray Absorption Spectroscopy (XAS): XAS provides information about the chemical form of heavy metals in a sample.
Sample Preparation:
Before analysis, samples (e.g., soil, water, biological tissues) often require preparation to ensure proper analysis.
This may involve digestion (e.g., using acids or microwave digestion), sample dilution, or extraction.
The choice of sample preparation method depends on the sample type, the metals being analyzed, and the analytical technique being used.
