The method is applicable in a concentration range from 0,005 \u00e6g\/l to 0,2 \u00e6g\/l for 4-(1,1,3,3-tetramethylbutyl)phenol and from 0,02 \u00e6g\/l to 0,2 \u00e6g\/l for 4-nonylphenol (mixture of isomers). Depending on the matrix, the method is also applicable to waste water in a concentration range from 0,1 \u00e6g\/l to 50 \u00e6g\/l.
