Heavy metals in coatings

The detection of heavy metals in coatings involves analyzing the content of metals such as lead, cadmium, and mercury through spectroscopic or electrochemical methods. This process is used to ensure that coating products meet safety standards and is applied in areas such as toys, building materials, and environmental regulation.
Selection
Based on the product's intended use and referencing national standards or EU RoHS limits, XRF spectroscopy is employed for rapid screening, while ICP-MS is used in the laboratory for precise verification. Regular calibration of equipment and verification of sample pretreatment procedures are conducted.
