DIN EN 13657 Digestion Testing for Chromatographic Analysis
The DIN EN 13657 standard provides a comprehensive approach to digestion testing specifically designed for chromatographic analysis. This method aims at enhancing the precision and reliability of analytical results by ensuring that all constituents in complex samples are sufficiently dissolved before being analyzed using gas or liquid chromatography.
This digestion process is crucial when dealing with matrices such as food, feed, pharmaceuticals, petrochemical products, and environmental samples where organic compounds may be present in varying forms. By subjecting these materials to acid-based or alkali-based digestion processes outlined in DIN EN 13657, analysts can break down complex molecules into simpler components that are more amenable to chromatographic separation.
The standard specifies several types of digestions tailored to different sample matrices and analytical goals:
- Strong Acid Digestion: Suitable for organic compounds resistant to less aggressive conditions.
- Weaker Acid Digestion: Ideal for samples containing higher proportions of inorganic elements that are not easily attacked by strong acids.
- Beta-Protease Digestion: Used when examining proteins or amino acids, providing a gentler digestion method compared to acid-based alternatives.
The digestion process is followed by thorough rinsing of the residue with deionized water and subsequent drying before analysis. This ensures that no residues remain which could interfere with chromatographic separation and detection.
The resulting solutions are then ready for quantitative or qualitative analysis using HPLC (High Performance Liquid Chromatography) or GC (Gas Chromatography), depending on the nature of the sample and the required outcome.
Accurate digestion is critical as even small amounts of undigested material can lead to inaccurate results. Proper technique and adherence to the standardized procedures outlined in DIN EN 13657 help minimize errors, thereby enhancing the overall quality and reliability of analytical data.
