Ambient air. Guide for the measurement of anions and cations in PM2,51 Scope This CEN Technical Report specifies a method for the determination of the mass of water soluble NO3 , SO4 2 , Cl , NH4 +, Na+, K+, Mg2+, Ca2+ in PM2,5 samples which can be used to comply with Directive 2008 50 EC. This CEN Technical Report describes a measurement method which comprises sampling of anions and cations as part of the PM2,5 particulate phase, sample extraction and analysis of anions and cations by ion chromatography.
