Continuous measurement of particulate nitrate |
| abstract |
A method for continuously measuring particulate nitrate in a gas sample, comprising the steps of passing the gas sample through an inertial impactor with a 50% cut off at 2.5 microns, removing ambient pollutant gases from the gas with diffusion denuders, passing the gas through a first path so as to contact the gas with a coated filter so as to convert particulate nitrate to nitric acid vapor or passing the gas through a second path so as to contact the gas with coated filters to trap particulate nitrate and ammonia, and measuring nitric acid vapor and residual ambient pollutant gases produced from the first path and residual ambient pollutant gases produced from the second path with a chemiluminescent monitor, the difference in the signal produced from the gases from the two paths being a measurement of the particulate nitrate in the gas sample. |
