标准范围

This International Standard specifies a method for the determination of volatile organic compounds(see Table 1). This comprises, for example, halogenated hydrocarbons, trihalogenated methanes,gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane,and highly odorous substances like geosmin and 2-methylisoborneol in drinking water, ground water,surface water, and treated waste water, by means of headspace solid-phase micro-extraction (HS-SPME)followed by gas chromatography-mass spectrometry (GC-MS). The limit of determination depends onthe matrix, on the specific compound to be analysed, and on the sensitivity of the mass spectrometer.For most compounds to which this International Standard applies, it is at least 0,01 μg/l. Validationdata related to a concentration range between 0,02 μg/l and 2,6 μg/l have been demonstrated in aninterlaboratory trial. Additional validation data derived from standardization work show applicabilityof the method within a concentration range from 0,01 μg/l to 100 μg/l of individual substances. Alldeterminations are performed on small sample amounts (e.g. sample volumes of 10 ml).This method may be applicable to other compounds not explicitly covered by this International Standardor to other types of water. However, it is necessary to demonstrate the applicability for each case.
