Water quality - Determination of parathion, parathion-methyl and some other organophosphorus compounds in drinking waters, ground waters and surface waters - Solid liquid extraction and gas chromatographic method

Scope

as follows: The standard specifies the extraction processes nd gas chromatographic (GC) methods for determining parathion, parathion-methyl and some other organophosphorus compounds in drinking waters, surface waters and waste waters. This standard may also be applicable for other organic compounds. The range is dependent on the compound and the source of water and is typically up to 1 micron g/l with a reporting limit of 0,01 micron g/l for drinking waters involving a 1000 to 1 extration ratio. The detailed performance of the method will be determined by an interlaboratory trial.
