What is EN ISO 11887:2009?

EN ISO 11887:2009 is a professional technical standard that provides guidelines for the determination of certain elements in water samples. This international standard, established by the International Organization for Standardization (ISO), outlines the procedures and methods for analyzing elements using various instrumental techniques.

The Importance of EN ISO 11887:2009

EN ISO 11887:2009 plays a crucial role in ensuring the reliability and comparability of analytical results obtained from different laboratories worldwide. It provides a standardized approach for the analysis of elements, allowing for accurate measurement and detection limits to be established. This is essential for assessing water quality and ensuring compliance with regulatory standards.

Analytical Techniques Covered by EN ISO 11887:2009

EN ISO 11887:2009 encompasses various analytical techniques commonly used in the determination of elements in water samples. These techniques include atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES), graphite furnace atomic absorption spectrometry (GFAAS), and inductively coupled plasma mass spectrometry (ICP-MS).

Steps Involved in Implementing EN ISO 11887:2009

Implementing EN ISO 11887:2009 involves several key steps. First, the selection of appropriate instruments and equipment is crucial. The standard provides details on instrument requirements and calibration procedures to ensure accurate and reliable measurements. Sample collection and preservation techniques are also outlined, emphasizing proper handling and storage to prevent sample contamination.

The standard then guides analysts through the preparation and digestion of water samples, specifying the use of suitable reagents and digestion methods. Analytical procedures, including instrumental settings and measurement techniques, are described in detail to ensure consistent and reproducible results. The data analysis and reporting requirements outlined in the standard further enhance the overall quality of water analysis.

In conclusion, EN ISO 11887:2009 is an essential technical standard that provides guidelines for the determination of elements in water samples. By following the procedures outlined in this standard, laboratories can ensure accurate and reliable measurement results, promoting a global understanding of water quality and compliance with regulatory standards.
