BS EN 16913:2017 specifies a method for the determination of the mass concentration of water
soluble NO3- (nitrate), SO42- (sulphate), Cl- (chloride), NH4+ (ammonium), Na+ (sodium), K+ (potassium),
Mg2+ (magnesium), Ca2+ (calcium) in PM2,5 as deposited on filters.
This European Standard describes the analytical procedures for determining anions and cations as part
of the PM2,5 particulate phase, sample extraction and analysis of anions and cations by ion
chromatography. Sampling onto filters will be done in accordance with EN 12341 for PM2,5.
NOTE 1 Alternatively, cations, excluding ammonium, can be analysed by inductively coupled plasma optical
emission spectrometry (ICP-OES). Ammonium can also be analysed by photometry or conductometry.
This European Standard can be used for the measurements of anions and cations as required by
Directive 2008/50/EC. The method does not take into account the possible losses during sampling due
to evaporation.
NOTE 2 NO3-, Cl-, NH4+ are part of the volatile fraction of PM2,5, and the concentrations determined using this
standard can be used as minimum values for the concentrations of these ions in PM2,5. NO3-, NH4+, Cl- are usually
up to 30 % underestimated due to evaporational losses from the filter during sampling.
