Brookhaven National Laboratory Filter Pack System for collection and determination of air pollutants
Technical Report
·
OSTI ID:6967007
A filter pack system for sampling trace constituents in the atmosphere from aircraft and ground based measurement platforms has been developed. The system simultaneously and quantitatively collects atmospheric aerosol, nitric acid and sulfur dioxide using three sequential filter stages. The aerosol filter can be analyzed for sulfate, nitrate, ammonium and hydrogen ions, and specifically for sulfuric acid. The nitric acid filter is analyzed for nitrate ion and the sulfur dioxide filter is analyzed for sulfate ion. Details of the procedures used for filter preparation, sampling, extraction and analysis are given. 7 refs.
