Water quality. Determination of individual isomers of nonylphenol. Method using solid phase extraction (SPE) and gas chromatography/mass spectrometry (GC/MS)1 Scope 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 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). Depending on the matrix, the method is also applicable to waste
