ISO 21833 Sample Preparation for Heavy Metal Analysis in Foods

ISO 21833 Sample Preparation for Heavy Metal Analysis in Foods: Eurolabs Testing Service

ISO 21833 is a widely accepted standard for sample preparation of food products intended for heavy metal analysis. This standard, published by the International Organization for Standardization (ISO), provides guidelines for the preparation of samples for analysis of heavy metals in foods.

The standard requires that laboratories follow specific procedures to ensure accurate and reliable results. These procedures include:

1. Sampling: The selection of representative samples from the food product.

2. Sample Preparation: The process of transforming the raw sample into a form suitable for analysis, including homogenization, digestion, and extraction.

3. Analysis: The measurement of heavy metal concentrations in the prepared sample using techniques such as atomic absorption spectroscopy (AAS), inductively coupled plasma mass spectrometry (ICP-MS), or other approved methods.

The standard is based on international and national regulations that govern food safety and quality. In the European Union, for example, the Regulation (EC) No 1881/2006 sets maximum levels for heavy metals in foods. Similarly, in the United States, the Food and Drug Administration (FDA) regulates the safety of food products, including limits on heavy metal contamination.

Eurolab is a leading laboratory testing service provider that offers ISO 21833 sample preparation services for heavy metal analysis in foods. Our team of experts follows strict guidelines to ensure compliance with international and national standards.

The need for ISO 21833 sample preparation for heavy metal analysis in foods arises from the potential risks associated with food contamination by heavy metals. Heavy metals such as lead, mercury, cadmium, and arsenic can be toxic to humans and animals, even at low concentrations.

Food products can become contaminated with heavy metals through various routes, including environmental pollution, industrial waste disposal, and agricultural practices. Consumers may unknowingly ingest these contaminants, leading to health problems.

The consequences of not performing this test are severe:

Eurolabs ISO 21833 sample preparation service involves the following steps:

1. Sample Receipt: The laboratory receives the food samples, which are then stored in a secure area until analysis.

2. Homogenization: The raw sample is homogenized to ensure uniform distribution of heavy metals.

3. Digestion: The homogenized sample is digested using a suitable acid mixture, depending on the type and concentration of heavy metals present.

4. Extraction: The digested sample is then extracted with a solvent to separate the heavy metal ions from the matrix.

5. Analysis: The extracted sample is analyzed using techniques such as AAS or ICP-MS.

Eurolab uses state-of-the-art equipment and follows strict quality control procedures to ensure accurate and reliable results.
