Heavy Metal Detection Service
Lead is a common harmful heavy metal that is widely found in various products. Due to its severe harm to human health, especially to the development of children's nervous systems, many countries have established strict lead content limit standards.
Through professional lead content testing, it can be ensured that products comply with relevant regulatory requirements and protect consumer health and safety.
The CPSIA Act in the United States stipulates that the lead content in paints and other surface coatings that can come into contact with children's products shall not exceed 90ppm, and the lead content in substrates of children's products produced after August 2021 shall not exceed 100ppm
The REACH Regulation of the EU stipulates that the lead content in decorative articles shall not exceed 0.05% (500ppm)
There are strict limits on the lead content in food contact materials in various countries, usually requiring it to be between 1-10ppm
The Packaging and Packaging Waste Directive of the EU stipulates that the lead content in packaging materials shall not exceed 100ppm
Currently, the most commonly used heavy metal detection method, with high sensitivity, high precision, and the advantage of simultaneous detection of multiple elements, with a detection limit reaching the ppt level
Traditional heavy metal detection methods, suitable for the precise determination of single elements, with good accuracy and stability
Quick screening method, no sample pretreatment required, non-destructive testing, suitable for preliminary screening of large batches of samples
Applicable for simultaneous detection of multiple elements, wide linear range, low detection limit, suitable for the analysis of various matrix samples
Lead content testing requires selecting the appropriate test standards and limit value requirements according to the product type and target market, and considering the actual usage and contact situation of the product.
