DIN 38407-7:2000-09

Describes methods to determine selected PAHs (see table 1) in drinking water [1] and in mineral and table water [2]. They may also be used to examine ground water and also slightly or moderately polluted surface water. Two methods are described: a) Method F 7-1, for identification, to exclude those samples whose PAH content is less than 25% of the limit specified in [1] and [2]. b) Method F 7-2, for quantification, for concentrations (combined total of six PAHs) from 40 ng/l to 240 ng/l. For higher concentrations (cf. sub clause 9.5.1), smaller aliquot volumes are to be used.
