适用范围：This European Standard specifies the extraction processes and gas chromatographic (GC) methods for determining parathion, parathion-methyl and some other organophosphorus compounds in drinking waters, surface waters and waste waters. This standard can also be suitable for the determination of other organic compounds. The range is dependent on the compound and the source of water and is typically up to 1 μg/l with a reporting limit of 0,01 μg/l for drinking waters involving a 1 000 to 1 extraction ratio. Extraction efficiencies are normally less than 100 %. Bias will vary with the extraction efficiency of any particular compound, the type of water and the method used. Annex A contains a table of organophosphorus compounds and their recoveries.
