Formation of aerosol particles from reactions of secondary and tertiary alkylamines: characterization by aerosol time-of-flight mass spectrometry

Article Abstract:

Aerosol particles are studied in a smog chamber and sampled near Riverside, California using aerosol time-of-flight mass spectrometry (ATOFMS) to find an effective method that may determine the major compounds in these particles, and the primary sources of aliphatic amine pollution. Ion peaks are graphed, and used to investigate the concentration aliphatic amines in the samples and possible sources are discussed.

Source apportionment of fine particulate matter by clustering single-particle data: tests of receptor model accuracy

Article Abstract:

Aerosol trajectory models for particulate emissions are constructed by researchers at the California Institute of Technology, Pasadena, using mass spectrometry measurements and neural network algorithms. The article details the model-building procedures and illustrates the result with multiple charts, graphs and statistics.
