Water quality - Determination of the dissolved fraction of selected active pharmaceutical ingredients, transformation products and other organic substances in water and treated waste water - Method using high performance liquid chromatography and mass spectrometric detection (HPLC-MS/MS or -HRMS) after direct injection (ISO 21676:2018)
This document sets a method for determining the dissolved proportion of selected drugs and transformation products as well as other organic substances (see Table 1) in drinking, basic, surface and treated wastewater. The lower scope of the method may vary depending on the sensitivity of the devices used and the matrix of the sample. For most connections for which this document is used, the range is greater than or equal to 0.025 g / l in drinking, base and surface water and greater than or equal to 0.050 g / l in treated wastewater. The method can be used to determine further organic substances or in other types of water (eg, thereto), if correctness in individual cases has been tested and detected and the storage conditions of samples and reference solutions were validated.
