Electrostatic particle collector
Satoshi Takahama, Nikunj Dudani
ESP particle collector (1) for collecting particles in a particle containing gas stream, comprising an inlet section (4), a collector section (6), and an electrode arrangement (8), the inlet section comprising a flow tube (10) defining a gas flow channel ( ...
2023Design and fabrication of an electrostatic precipitator for infrared spectroscopy
Satoshi Takahama, Nikunj Dudani
Infrared (IR) spectroscopy is a direct measurement technique for chemical characterization of aerosols that can be applied without solvent extraction thermal treatment a priori. This technique has been used for chemical speciation, source apportionment, an ...
COPERNICUS GESELLSCHAFT MBH2022Fragment ion-functional group relationships in organic aerosols using aerosol mass spectrometry and mid-infrared spectroscopy
Satoshi Takahama, Imad El Haddad, Nikunj Dudani, Amir Yazdani
Aerosol mass spectrometry (AMS) and mid-infrared spectroscopy (MIR) are two analytical methods for characterizing the chemical composition of OM. While AMS provides high-temporal-resolution bulk measurements, the extensive fragmentation during the electron ...

2022Design and fabrication of an aerosol collector for infrared spectroscopy analysis
Particulate matter (PM) pollution causes adverse health effects and millions of deaths each year. PM or aerosol, is difficult to characterize because of its wide range of particle sizes, constituents (various organic and inorganic compounds), concentration ...
EPFL2021Characterization of primary and aged wood burning and coal combustion organic aerosols in an environmental chamber and its implications for atmospheric aerosols
Satoshi Takahama, Imad El Haddad, Nikunj Dudani, Amir Yazdani
Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM mass. We investigated the effect of aging on secondary organic aerosol (S ...
