• Precise Nitrogen Quantification: The Dumas combustion method provides reliable, reproducible results for total nitrogen content, enabling you to make informed decisions about your products.
• Compliance with Regulations: Adherence to this British Standard ensures your nitrogen analysis meets the stringent requirements of food and feed legislation, avoiding costly non-compliance issues.
• Streamlined Testing Processes: The standardized methodology outlined in this document simplifies your testing procedures, saving time and resources while maintaining the highest levels of accuracy.
• Versatile Application: This standard can be applied to a wide range of food matrices, including dairy products, meat, seafood, cereals, and more, as well as animal feeds and pet foods.

Comprehensive Guidance for Nitrogen Analysis

BS EN ISO 16634-2:2016 provides detailed instructions on the Dumas combustion method, covering everything from sample preparation to data analysis. The standard includes the following key sections:

Scope

This standard specifies a method for the determination of the total nitrogen content in food products and animal feeds using the Dumas combustion technique. It is applicable to a wide range of food and feed matrices.

Principle

The Dumas combustion method involves the complete and instantaneous oxidation of the sample in a pure oxygen atmosphere. The resulting combustion gases are then measured using a thermal conductivity detector to determine the total nitrogen content.

Apparatus

The standard outlines the required equipment, including a Dumas combustion analyzer, balance, desiccator, and various glassware and consumables.

Procedure

Detailed step-by-step instructions are provided for sample preparation, calibration, and the Dumas combustion analysis process, ensuring consistent and reliable results.

Calculation and Expression of Results

The standard explains how to calculate the total nitrogen content based on the measured values, as well as the appropriate units and reporting format.

Precision and Bias

Statistical data on the method's precision, including repeatability and reproducibility, is included to help users interpret their results with confidence.

By following the comprehensive guidance in BS EN ISO 16634-2:2016, food and feed producers, as well as testing laboratories, can ensure their nitrogen analysis is accurate, compliant, and aligned with the latest industry best practices.
