EN 19934 Validation of Trace Mineral Methods for Food Laboratories
The European Standard EN 19934 provides a framework for validating trace mineral methods in food laboratories. This service is designed to ensure the accuracy and reliability of analytical results, which is crucial for maintaining high standards in food safety and quality assurance.
Trace minerals such as iron, zinc, copper, manganese, and selenium are essential nutrients that play vital roles in various biological processes within humans and animals. However, their presence must be carefully monitored to ensure they do not exceed safe levels which could lead to toxicity or other health issues. Therefore, the validation of trace mineral methods is paramount.
The EN 19934 standard outlines a comprehensive process for validating analytical methods used in determining trace elements in food products. This includes selecting appropriate reference materials, establishing detection limits, assessing linearity over specified concentration ranges, demonstrating precision and accuracy through replicate analyses, and ensuring robustness against interferences.
The validation process ensures that the methods employed by laboratories meet stringent quality control criteria set forth by international standards organizations such as ISO (International Organization for Standardization). By adhering to these standards, food manufacturers can have confidence in their analytical data, thereby enhancing consumer trust and regulatory compliance.
Our team of experts utilizes advanced instrumentation including ICP-MS (Inductively Coupled Plasma Mass Spectrometry) systems to perform rigorous validation exercises according to EN 19934 guidelines. Each step of the procedure is meticulously documented and reviewed by our qualified personnel before final results are generated.
In summary, this service offers unparalleled assurance that your laboratory’s trace mineral analysis procedures adhere strictly to established protocols, ensuring precision and reliability in every result produced. This not only supports robust quality management practices but also facilitates smoother interactions with regulatory bodies such as the European Food Safety Authority (EFSA).
Scope and Methodology
| Aspect | Description |
|---|---|
| Selection of Reference Materials | EN 19934 recommends the use of certified reference materials that cover a wide range of trace mineral concentrations relevant to food matrices. |
| Detection Limits | The standard specifies minimum detectable limits for each trace element, ensuring that methods can accurately quantify even minute quantities present in complex mixtures typical of foods. |
| Linear Range Assessment | This involves evaluating the relationship between analyte concentration and measured response across a defined interval, confirming consistent behavior within this range. |
| Precision and Accuracy Checks | Averaging multiple replicates of identical samples helps determine both intra-assay precision (repeatability) and inter-assay precision (reproducibility). |
| Robustness Evaluation | The impact of minor variations in operating conditions or sample preparation is assessed to ensure robust results under realistic laboratory environments. |
