BS EN 16913 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.
BS EN 16913 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.
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.
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.
BS EN 16913 on ambient air is relevant to:
Ambient air is atmospheric air in its natural state, that is, air that has not been contaminated by pollution.
BS EN 16913 provides methods and procedures that allows determining anions (Cl-, NO3- and SO42-) and cations (Na+, NH4+, K+, Mg2+ and Ca2+) in PM2,5 collected on filters used for sampling ambient air.
Following BS EN 16913 guidelines, you will be able to make a periodic measurement of particulate matter emissions from different sources.
BS EN 16913 addresses methods for sampling filter materials, handling the samples and analysing the properties of the samples, as well as temperature and time limits of sampling, which enable manufacturers of air filters to evaluate the quality and strength of the filters.
In BS EN 16913, performance criteria and test procedures for measuring air quality are provided to test and manufacture air quality measuring devices and provide an improved solution for harmful gasses emitted by different sources, which are very toxic.
BS EN 16913 specifies the specifications and test methods necessary, which will help you manufacture high quality, durable, and efficient air filters to help collect toxins and dust particles from the air.
