Paper Heavy Metal Testing
Heavy metal testing in paper is crucial for ensuring compliance with environmental regulations and consumer safety standards. Heavy metals such as lead, mercury, cadmium, and chromium can be present in various forms within the paper manufacturing process, from raw materials to final products. These elements may originate from wood pulp, ink formulations, or even unintentional contamination during processing.
The testing of heavy metals in paper helps identify any potential health risks associated with prolonged exposure, particularly for sensitive populations such as children and pregnant women. The presence of these contaminants can lead to adverse effects on human health, including neurological damage, kidney function impairment, and immune system suppression.
Our laboratory offers comprehensive services that ensure accurate detection and quantification of heavy metals in paper samples. Our team utilizes advanced analytical techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Flame Atomic Absorption Spectroscopy (FAAS), which provide precise results even at trace levels.
For comprehensive testing, we recommend submitting representative samples that include both the paper itself and any additives used in its production. This allows us to assess not only the intrinsic properties of the paper but also the potential for contamination introduced during manufacturing processes.
The process involves several key steps:
- Sample preparation
- Extraction of heavy metals from the sample matrix
- Analytical determination using ICP-MS and FAAS
- Data interpretation and reporting
Our services cater specifically to quality managers, compliance officers, R&D engineers, and procurement professionals who need reliable data regarding heavy metal content in their paper products. By providing accurate test results, we assist these stakeholders in making informed decisions about raw material sourcing, process optimization, and product safety.
| Heavy Metal | Detected Limits (ppm) |
|---|---|
| Cadmium (Cd) | <0.1 |
| Lead (Pb) | <5 |
| Mercury (Hg) | <0.2 |
| Copper (Cu) | <10 |
