Method ID-165SG

Acid Mist by IC

This method describes the collection and analysis of airborne acids using Ion Chromatography. The method measures the total concentration of four airborne anions. The corresponding acids may be collected on a single sampler and determined simultaneously. Acids which can be collected and analyzed this way are hydrobromic acid, phosphoric acid, nitric acid, and sulfuric acid. A known volume of air is drawn through a silica gel tube. Sulfuric acid, phosphoric acid and other particulates are collected on the glass fiber plug while hydrobromic acid and nitric acid are collected on the silica gel sorbant. The glass fiber plug and the silica gel tubes are desorbed with standard eluent and analyzed by Ion Chromatography (IC).
