AN1107: Determination of Anions and Carboxylic Acids in Urban Fine Particles (PM2.5)
Description
Ionic forms of air pollutants are analyzed here using anion-exchange chromatography and suppressed conductivity. The gas sample included particles < 2.5 um (PM2.5) was collected using ambient ion monitoring and then dissolved in deionized water. The dissolved inorganic anions and organic acids were separated on a 4 mm i.d. IonPac AS11-HC column and detected by suppressed conductivity. This method provided analysis of more ionic contaminants than standard methods (EPA Method 26A) and ASTM D5085-02). An ICS-6000 can be used for this application.| Market: | Environmental |
