BS EN 16159:2012

Overview

BS EN 16159:2012 specifies a method for the determination of selenium in animal feeding stuffs using hydride generation atomic absorption spectrometry (HGAAS) following microwave digestion. This standard is essential for ensuring the accurate measurement of selenium levels, which is crucial for animal health and compliance with regulatory requirements.

Key Requirements

The standard outlines a systematic approach to sample preparation and analysis. Key requirements include:

• Sample Preparation: Samples must be digested using a mixture of 65% nitric acid and 30% hydrogen peroxide in a microwave digestion system. This ensures complete dissolution of the sample matrix.
• Hydride Generation: The method employs hydride generation to convert selenium into a volatile hydride, which is then introduced into the atomic absorption spectrometer for detection.
• Calibration and Quality Control: Laboratories must establish calibration curves and implement quality control measures to ensure the accuracy and reliability of results.

Implementation Benefits

Adopting BS EN 16159:2012 provides several practical benefits:

• Enhanced Accuracy: The use of microwave digestion combined with HGAAS allows for precise measurement of selenium, reducing the risk of underestimation or overestimation.
• Regulatory Compliance: Compliance with this standard helps manufacturers meet legal requirements regarding the safety and quality of animal feed, thereby protecting animal health and consumer interests.
• Improved Laboratory Efficiency: The standardisation of procedures facilitates consistent results across different laboratories, enhancing collaboration and data sharing.

Compliance Value

Compliance with BS EN 16159:2012 is critical for businesses involved in the production and testing of animal feeding stuffs. Key compliance values include:

• Legal Assurance: Adhering to this standard mitigates the risk of non-compliance with food safety regulations, which can lead to legal repercussions and financial penalties.
• Market Confidence: Demonstrating compliance with recognised standards builds trust with customers and stakeholders, enhancing the reputation of the business.
• Risk Management: Regular testing and adherence to this standard help identify potential risks associated with selenium levels in animal feed, allowing for proactive management and mitigation strategies.

In conclusion, BS EN 16159:2012 is a vital standard for the determination of selenium in animal feeding stuffs. Its implementation not only ensures compliance with regulatory frameworks but also enhances the overall quality and safety of animal feed products.
