scope:

This International Standard specifies a method for the determination of the dissolved amount of selected plant treatment agents and biocide products in drinking water, ground water and surface water by solid-phase microextraction (SPME) following gas chromatography mass spectrometry (GC-MS) . The lower limit of the working range depends on the matrix, on the specific compound to be analysed and on the sensitivity of the mass spectrometric detection unit. For most compounds in Table 1 it is at least 0,05 ìg/l. Validated procedural data related to a concentration range between 0,05 ìg/l and 0,3 ìg/l are given in Table C.1. This method may be applicable as well to compounds not mentioned in Table 1 or to other types of water. However, it is necessary to verify the applicability of this method for these special cases. NOTE Determinations by this International Standard require small sample amounts (e.g. sample volumes between 8 ml and 16 ml).
