EN ISO 11885:2007+A1:2013 is an international standard that provides guidelines for the determination of certain elements. It specifically addresses the determination of trace elements in water samples using atomic absorption spectrometry with hydride generation (HG-AAS) or cold vapor generation (CVG-AAS). This standard plays a crucial role in ensuring accurate and reliable measurements of trace elements, which are essential for various industries and environmental monitoring.
Importance of EN ISO 11885:2007+A1:2013
Accurate measurement of trace elements in water samples is essential for several reasons. Firstly, it helps in assessing water quality and ensuring it meets relevant regulatory standards. Trace elements, even in small concentrations, can have significant impacts on human health if consumed through drinking water or accumulated in aquatic ecosystems. Therefore, adhering to the guidelines outlined in EN ISO 11885:2007+A1:2013 is crucial to protect public health and preserve the environment.
The Analytical Process
The standard outlines a comprehensive analytical process for determining trace elements in water samples. It includes sample collection, preservation, and pre-treatment methods. The determination of trace elements using HG-AAS or CVG-AAS involves specialized techniques that require careful calibration, instrument operation, and data analysis. The standard provides detailed instructions on these aspects, ensuring consistency and comparability of results obtained by different laboratories.
Benefits and Limitations
Adhering to EN ISO 11885:2007+A1:2013 offers several benefits. Firstly, it enhances the reliability and accuracy of trace element measurements, reducing the risk of erroneous results. Consistent application of the standard across different laboratories allows for reliable comparison and interpretation of data. However, it is important to note that the standard has certain limitations. It does not cover all possible elements or analytical techniques, and there may be specific considerations for certain types of water samples or trace elements not covered in the standard.
