Determination of Anions and Carboxylic Acids in Urban Fine Particles (PM_2.5)

Identifying the composition of ambient PM_2.5 plays an important role in air quality management. This application note demonstrates the development of an efficient IC method for the sensitive determination of inorganic anions and carboxylic acids (fluoride, acetate, formate, mesylate, chloride, nitrate, succinate, malonate, sulfate, and oxalate) in airborne PM_2.5 using the Thermo Scientific™ Dionex™ ICS-5000+ Reagent-Free™ HPIC™ system.
