WLN-CO.W.42.1Determination of the amount of diethyl ether-extractable compounds in water by means of on-column injection, gas chromatography and mass-selective detection (QQQ).in-house method
Principle:NaCl, sodium tartrate, methanol, extractant and internal standards are added to a sample. After extraction, the extract is examined by PTV injection, capillary gas chromatography and mass selective detection (triple quad). Identification and quantification takes place by as specific as possible mass transitions, by comparing the retentiontimes and areas. This is corrected for the internal standards. Except PCB-29 all internal standards are labeled.
Determination:Aromatic amines
Performance characteristics:
Matrices qualified by the Dutch RvA:Drinking water, Groundwater, Surface water
Reporting limit:0.05 - 0.1 μg/l, parameter and matrix dependent
Measurement uncertainty:30%
Sustainability:1 day
Sampling bottle:Glass , brown , 100 ml (fill up to the neck of the bottle)
