eng Abstract:
Carbonaceous aerosols form a major part of particulate matter suspended in the atmosphere. The organic part of aerosol represents a diverse group of substances that can be analyzed in different ways. In this work, the possible linkages between organic fractions measured by Compact Time-of-Flight Aerosol Mass Spectrometer (AMS; from Aerodyne) and a semi-online EC/OC analyzer (from Sunset Laboratories) were search. Each of these instruments provides a different kind of information. Organic fractions from EC/OC analyzer provide knowledges about a diferent volatility of organic carbon (OC) while AMS provide informations about a chemical composition of characteristic mass fragments. Thus, the main objective of this work was to determine whether the organic fractions from EC/OC analyzer can indirectly provide also information on the chemical composition or somehow more characterize type of aerosol.
