Water quality - Determination of selected phenoxyalkanoic herbacides, including bentazones and hydroxybenzonitriles by gas chromatography and mass spectrometry after solid phase extraction and derivatization
This standard specifies a method for the determination of phenoxyalkanoic acids in ground and drinking water in mass concentrations 50 ng/l (detailed information is given in Table A.1 of annex A). Examples of phenoxyalkanoic acids which can be determined by this method are given in Table 1.
