Detection of particle-phase polycyclic aromatic hydrocarbons in Mexico City using an aerosol mass spectrometer

We report the quantification of ambient particle-bound polycyclic aromatic hydrocarbons (PAHs) for the first time using a real-time aerosol mass spectrometer. These measurements were carried out during the Mexico City Metropolitan Area field study (MCMA-2003) that took place from March 29 to May 4, 2003. This was the first time that two different fast, real-time methods have been used to quanti...

Organic particle types by single - particle measurements using a time - of - flight aerosol mass spectrometer coupled with a light scattering module

Use of a Thermal Desorption Particle Beam Mass Spectrometer for Studies of Secondary Organic Aerosol Formation

As part of a research program focusing on studies of the chemistry of gas-to-particle conversion, we have recently developed a new instrument for particle chemical analysis. This instrument, which we refer to as a thermal desorption particle beam mass spectrometer (TDPBMS), can be used for real-time, quantitative analysis of the components of organic particles, at least within the ~0.02-0.5 mic...

STUDIES with the AEROSOL MASS SPECTROMETER

Fast time-response of the Aerodyne Aerosol Mass Spectrometer (AMS) makes it a well-suited instrument for ambient field measurements. On the other hand, laboratory chamber experiments provide the opportunity to study a specific system in a more controlled environment. The goal of this thesis is to provide a summary of laboratory and field measurements using the AMS. During laboratory chamber pho...
