To better understand aerosol composition, chemical association, and size distribution, our group often takes portable ATOFMS’s on a field trip to take ambient measurements at various locations on the continental US, we’ve even loaded the instruments on ships and taken measurements in the open ocean. The ATOFMS detects aerodynamic diameter and chemical composition of individual particles and thus providse information on, but not limited to, major particle classes and chemical association, temporal variation of chemical classes, and particle size distribution. Being capable of providing high time resolution data, the ATOFMS can capture instantaneous ambient events that are sometimes challenging for other techniques to detect.
