ISO 11212 Lead Analysis in Food by Atomic Absorption Spectrometry
The ISO 11212 standard provides a robust methodology for the determination of lead (Pb) in foods and feedstuffs using atomic absorption spectrometry. This service is critical to ensuring that food products comply with international safety standards, thereby protecting public health.
Lead contamination can occur through various means such as soil, water, air, or packaging materials used during production. Lead is a toxic element that poses significant risks if ingested by humans and animals, especially in high concentrations. Compliance with ISO 11212 ensures that food products meet regulatory requirements and maintain consumer trust.
The test process involves several key steps: sample preparation, digestion, and finally, analysis via atomic absorption spectrometry (AAS). Sample preparation requires thorough homogenization to ensure accurate results. Digestion is performed using strong acids like nitric acid under controlled conditions to release lead from the matrix for measurement.
Once digested, the sample solution is introduced into an AAS instrument equipped with a hollow cathode lamp (HCL) specific to lead. The HCL emits light at wavelengths corresponding to the absorption spectrum of lead atoms. As the sample passes through this light source, any lead present absorbs some of the light, creating measurable changes in intensity. By comparing these intensities against calibration standards containing known amounts of lead, precise concentrations can be determined.
This service is not only about detecting lead but also ensuring its concentration falls within acceptable limits as defined by international regulations such as EU Directive 2017/625 and Codex Alimentarius. The results from this analysis are highly reliable due to the precision of AAS coupled with rigorous adherence to ISO 11212.
Our laboratory adheres strictly to all relevant standards including ISO 11212, ensuring accurate and consistent testing across various types of food products ranging from fruits and vegetables to processed meats. We employ experienced scientists who maintain thorough documentation throughout the entire process to ensure traceability and reproducibility.
| Sample Type | Expected Detection Limits (ppb) |
|---|---|
| Fruits & Vegetables | <0.5 ppb |
| Dairy Products | <1.0 ppb |
| Meat & Poultry | <2.5 ppb |
