Measurements of Gaseous NH3 and Particulate NH4 + in the Atmosphere by Fluorescent Detection after Continuous Air–water Droplet Sampling
Ammonia Gas-particle partitioning Microflow analysis Short-term variation
2016/3/28
Phase partitioning of NHx (gaseous NH3 and particulate NH4
+) in the atmosphere is crucial for the lifetime of NHx
during atmospheric transport. Reliable data for gaseous NH3 and NH4
+ in aerosols ...
