DANSK DSF/ISO/FDIS 21676 PDF

This document specifies a method for the determination of the dissolved fraction of selected active pharmaceutical ingredients and transformation products as well as other organic substances (see Table 1) in drinking water, ground water and surface water at mass concentrations ≥ 0,025 μg/l and in treated waste water at mass concentrations ≥ 0,050 μg/l. The lower application range of this method can vary depending on the sensitivity of the equipment used and the matrix of the sample. The method can be used to determine further organic substances or in other types of water provided that accuracy has been tested and verified for each case as well as storage conditions of both samples and reference solutions have been validated. Please refer to Table E.1 for examples of determining other organic substances.
