AOAC 2015 Heavy Metal Testing by Chromatography
The AOAC International (Association of Official Analytical Chemists) developed Standard Method 996.17-2015 provides a method for the determination of heavy metals in various food and feed products using high-performance liquid chromatography (HPLC) with inductively coupled plasma mass spectrometry (ICP-MS). This service is crucial for ensuring compliance with global regulatory standards and for safeguarding public health by detecting trace levels of harmful elements.
The method involves several key steps: sample preparation, digestion, filtration, and injection into the HPLC system. The chromatographic separation allows for the detection of heavy metals at extremely low concentrations, which is essential for meeting stringent international regulatory thresholds such as those set by the European Union (EU) or the United States Food and Drug Administration (FDA).
The service includes comprehensive sample preparation protocols to ensure accurate results. These involve digestion using nitric acid, followed by filtration through a 0.45 µm filter. The prepared samples are then injected into an HPLC system equipped with a column optimized for heavy metal analysis. Detection is performed via ICP-MS, which provides high sensitivity and selectivity.
For quality assurance, we adhere to strict calibration procedures using certified reference materials (CRMs). This ensures that the method produces accurate results consistently across different samples. The service also includes detailed reporting of all test parameters, including detection limits, quantitation limits, and any deviations from expected values.
The AOAC 2015 Heavy Metal Testing by Chromatography is a critical tool for industries dealing with food safety, ensuring that products meet stringent regulatory requirements. By detecting trace levels of heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), and arsenic (As), this service helps prevent contamination risks and protects consumer health.
