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...
متن کاملField-deployable, high-resolution, time-of-flight aerosol mass spectrometer.
The development of a new high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is reported. The high-resolution capabilities of this instrument allow the direct separation of most ions from inorganic and organic species at the same nominal m/z, the quantification of several types of organic fragments (CxHy, CxHyOz, CxHyNp, CxHyOzNp), and the direct identification of organic nitr...
متن کاملCharacterization of the South Atlantic marine boundary layer aerosol using an Aerodyne Aerosol Mass Spectrometer
Measurements of the submicron fraction of the atmospheric aerosol in the marine boundary layer were performed from January to March 2007 (Southern Hemisphere summer) onboard the French research vessel Marion Dufresne in the Southern Atlantic and Indian Ocean (20 S–60 S, 70 W–60 E). We used an Aerodyne HighResolution-Time-of-Flight AMS to characterize the chemical composition and to measure spec...
متن کاملAerosol quantification with the Aerodyne Aerosol Mass Spectrometer: detection limits and ionizer background effects
Systematic laboratory experiments were performed to investigate quantification of various species with two versions of the Aerodyne Aerosol Mass Spectrometer, a Quadrupole Aerosol Mass Spectrometer (Q-AMS) and a compact Time-of-Flight Aerosol Mass Spectrometer (c-ToFAMS). Here we present a new method to continuously determine the detection limits of the AMS analyzers during regular measurements...
