BS EN ISO 14690:2013 is a technical standard that pertains to the analytical determination of trace elements in water. This international standard provides guidelines and requirements for sample collection, preservation, storage, and analysis methods to ensure accurate and reliable measurements of trace elements. In this article, we will explore the key aspects of BS EN ISO 14690:2013.
Sample Collection and Preservation
One of the crucial steps in analyzing water samples for trace elements is proper sample collection and preservation. BS EN ISO 14690:2013 outlines specific procedures to minimize contamination and preserve the integrity of the collected samples. It emphasizes the use of clean, non-contaminating equipment and containers, as well as ensuring representative sampling techniques.
The standard also highlights the importance of sample preservation techniques to prevent alteration or loss of analytes during storage. Various preservation methods, such as acidification, refrigeration, and filtration, are recommended based on the specific analytes and their stability characteristics.
Analytical Methods and Quality Assurance
BS EN ISO 14690:2013 encompasses a wide range of analytical methods for determining trace elements in water. These methods include atomic absorption spectrometry (AAS), inductively coupled plasma-mass spectrometry (ICP-MS), and voltammetry, among others. The standard specifies the requirements for instrumentation, calibration, and validation of these methods to ensure accurate and precise measurements.
Quality assurance is a vital aspect of any analytical procedure, and BS EN ISO 14690:2013 provides comprehensive guidelines for establishing quality control measures. This includes the use of certified reference materials, participation in proficiency testing programs, and regular calibration checks to monitor the accuracy and reliability of the analytical results.
Applications and Benefits
BS EN ISO 14690:2013 is applicable to a wide range of industries and sectors that require accurate analysis of trace elements in water. This includes environmental monitoring, drinking water analysis, industrial wastewater treatment, and research laboratories, among others.
By adhering to the guidelines outlined in BS EN ISO 14690:2013, organizations can ensure the reliability and comparability of their analytical results. This standard enables harmonization of analytical practices, facilitating data exchange and comparison between different laboratories and institutions. Additionally, it contributes to enhancing the overall quality of water analysis and supports informed decision-making processes.
In conclusion, BS EN ISO 14690:2013 plays a crucial role in standardizing the analytical determination of trace elements in water. It provides guidelines for sample collection, preservation, analytical methods, and quality assurance. By following these guidelines, organizations can obtain accurate and reliable data, contributing to improved water quality monitoring and management.
