BS EN 16691:2015

This European Standard specifies a method for the determination of 7 polycyclic aromatic hydrocarbons (PAH) in whole water samples listed in Table1. The method uses solid-phase disk extraction with SPE-disks followed by gas chromatography-mass spectrometry (GC-MS). It is applicable to the analysis of PAHs in surface water containing suspended particulate matter (SPM) up to 500mg/l (whole water samples), drinking water and groundwater. The lower and upper limit of the working range depends on the matrix, on the specific compound to be analyzed and on the sensitivity of the mass spectrometric detection unit. The limit of quantification (LOQ) determined in the validation is given in Table1. The upper limit of the working range is approximately 2000ng/l. This method is, with some modifications suitable for the analysis of waste water. This method is applicable to other PAH 1) , provided the method is validated for each PAH.
