BS ISO 21675:2019 - Water Quality Standard

Ensure the highest standards of water quality with the BS ISO 21675:2019, a comprehensive guideline for the determination of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water. This standard is an essential resource for laboratories, environmental agencies, and industries involved in water quality testing and monitoring.

Overview

The BS ISO 21675:2019 standard provides a detailed methodology for the detection and quantification of PFAS in water samples. PFAS are a group of man-made chemicals that have been widely used in various industrial applications and consumer products. Due to their persistence in the environment and potential health risks, accurate detection and monitoring of these substances are crucial.

Methodology

This standard outlines a method using solid phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS). This advanced analytical technique ensures precise and reliable results, making it a preferred choice for professionals in the field of water quality analysis.

BS ISO 21675:2019

This standard BS ISO 21675:2019 Water quality. Determination of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water. Method using solid phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS) is classified in these ICS categories:

• 13.060.50 Examination of water for chemical substances

This document specifies a method for the determination of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in non?filtrated waters, for example drinking water, natural water (fresh water and sea water) and waste water containing less than 2 g/l solid particulate material (SPM) using liquid chromatography-tandem mass spectrometry (LC?MS/MS). The compounds monitored by this method are typically the linear isomers. The group of compounds determined by this method are representative of a wide variety of PFAS. The analytes specified in Table 1 can be determined by this method. The list can be modified depending on the purpose for which the method is intended. The lower application range of this method can vary depending on the sensitivity of the equipment used and the matrix of the sample. For most compounds to which this document applies ?0,2 ng/l as limit of quantification can be achieved. Actual levels can depend on the blank levels realized by individual laboratory.

The applicability of the method to further substances, not listed in Table 1, or to further types of water is not excluded, but is intended to be validated separately for each individual case.
