Saturation of the IMPROVE denuder for SO2 and HNO3
Eldred R. 1998. Saturation of the IMPROVE denuder for SO2 and HNO3. CNL, University of California. Davis, CA
The IMPROVE denuder has a collection efficiency for SO2 of >99% when freshly coated. There is some question about whether there is breakthrough of SO2 and HNO3 after being used for a year, at least at sites with high SO2 concentrations. This report examines the effect of breakthrough of SO2 on the sulfate measurements and of HNO3 on the nitrate measurements.
