Analysis of individual inorganic salt particles using aerosol time-of-flight mass spectrometry (ATOFMS)
- Univ. of California, Riverside, CA (United States)
The chemical composition of tropospheric aerosols results from the interactions of many formative and dynamic processes. For this reason, atmospheric particles are often composed of several materials and composition varies as a function of time and location. A large amount of particulate matter found in the environment is composed primarily of inorganic salts. These salts are of environmental interest due to their connection to atmospheric acidity and photochemical smog. However, very little is known about the chemistry these compounds undergo in the particle phase or how variations in atmospheric conditions such as pH and relative humidity play a role in these processes. Aerosol Time-of-Flight Mass Spectrometry (ATOFMS) provides a means by which these particles can be studied in real time. This poster presents work carried out on the characterization of inorganic salt particles containing nitrates, phosphates, and sulfates using ATOFMS.
