WLN-CO.W.02.1	Determination of volatile organic components by means of head-space and GC-MS	in-house method
Principle:	A water sample is heated. The volatile compounds are injected from the head-space, trapped on a cold-trap and by thermal desorption transferred to the analytical column. The volatile compounds are gaschromatically separated and detected by a mass selective detector.
Determination:	Very volatile organohalogenated comp.
Performance characteristics:
Matrices qualified by the Dutch RvA:	Drinking water, Groundwater, Surface water
Reporting limit:	0.05 - 0.5 μg/l, parameter and matrix dependent
Measurement uncertainty:	35%
Sustainability:	7 days , if conserved with H2SO4
Sampling bottle:	Glass , brown , 200 ml , conservation with H2SO4 (fill up to cap)
