Matrices qualified by the Dutch RvA:	Wastewater, Drinking water, Groundwater, Surface water
Reporting limit:	1 mg/l, matrix dependent
Measurement uncertainty:	40%
Sustainability:	7 days , if conserved with H2SO4
Sampling bottle:	Glass , white , 100 ml , conservation with H2SO4 (fill up to the neck of the bottle)
