Water quality - Determination of individual isomers of nonylphenol - Method using solid phase extraction (SPE) and gas chromatography/mass spectrometry (GC/MS)
This International Standard specifies a method for the determination of selected individual isomers of*nonylphenol in non-filtered samples of drinking water, waste water, ground water and surface water. The analytes specified in Table 1 can be determined by this method. A total of thirteen isomers (eleven identified isomers and two isomers with tentative identification) constitute more than 90 % of nonylphenol isomers that are detectable in technical preparations and in environmental samples in general. The method is applicable in*concentrations between 0,001 ∞g/l and 0,1 ∞g/l for individual isomers and from 0,01 ∞g/l to 0,2 ∞g/l for the sum of 4-nonylphenol (mixture of isomers (5.1)). Depending on the matrix, the method is also applicable to waste water in concentrations between 0,1 ∞g/l and 50 ∞g/l. Water samples containing more than 500 mg/l of suspended matter and waste water samples are extracted by passing 100 ml of the sample through the cartridge (5.2)).
