Characterisation of sludges - Determination of nonylphenols (NP) and nonylphenol-mono-and diethoxylates in sludges, using gas chromatography with mass selective detection

Scope

This international standard describes a method for the determination of nonylphenols (NP), nonylphenol monoethoxylates and nonylphenol diethoxylates in soil, sludge and compost using GC/MS. Shall 4-tert-octylphenol be included?
The standard primarily describes the analysis of sludge, soil and compost. Other solid materials like sediment and selected solid wastes may also be analysed by the method. For sludge and compost a limit of detection of 0,1 mg/kg and for soil 0,01-0,02 mg/kg
(expressed as dry matter) may be achieved. The exact LOD will be determined by the method validation. Matrices for which the standard
has been validated are listed in Annex A. Lower LOD's may be achieved by concentrating the extract by solvent evaporation.
