Machine learning approaches for automatic classification of single-particle mass spectrometry data

Autor: G. Wang, H. Ruser, J. Schade, J. Passig, T. Adam, G. Dollinger, R. Zimmermann

Publikováno v: Atmospheric Measurement Techniques, Vol 17, Pp 299-313 (2024)

The chemical composition of aerosol particles is a key parameter for human health and climate effects. Single-particle mass spectrometry (SPMS) has evolved to a mature technology with unique chemical coverage and the capability to analyze the distrib

Autor: J. Passig, J. Schade, R. Irsig, T. Kröger-Badge, H. Czech, T. Adam, H. Fallgren, J. Moldanova, M. Sklorz, T. Streibel, R. Zimmermann

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 1495-1514 (2022)

We investigated the distribution of polycyclic aromatic hydrocarbons (PAHs) on individual ambient aerosol particles at the Swedish western coast in a pristine environment for 10 d in October 2019. The measurements were carried out using new technolog

Detection of ship plumes from residual fuel operation in emission control areas using single-particle mass spectrometry

Autor: J. Passig, J. Schade, R. Irsig, L. Li, X. Li, Z. Zhou, T. Adam, R. Zimmermann

Publikováno v: Atmospheric Measurement Techniques, Vol 14, Pp 4171-4185 (2021)

Ships are among the main contributors to global air pollution, with substantial impacts on climate and public health. To improve air quality in densely populated coastal areas and to protect sensitive ecosystems, sulfur emission control areas (SECAs)

Resonance-enhanced detection of metals in aerosols using single-particle mass spectrometry

Autor: J. Passig, J. Schade, E. I. Rosewig, R. Irsig, T. Kröger-Badge, H. Czech, M. Sklorz, T. Streibel, L. Li, X. Li, Z. Zhou, H. Fallgren, J. Moldanova, R. Zimmermann

Publikováno v: Atmospheric Chemistry and Physics, Vol 20, Pp 7139-7152 (2020)

We describe resonance effects in laser desorption–ionization (LDI) of particles that substantially increase the sensitivity and selectivity to metals in single-particle mass spectrometry (SPMS). Within the proposed scenario, resonant light absorpti

Dynamic changes in optical and chemical properties of tar ball aerosols by atmospheric photochemical aging

Autor: C. Li, Q. He, J. Schade, J. Passig, R. Zimmermann, D. Meidan, A. Laskin, Y. Rudich

Publikováno v: Atmospheric Chemistry and Physics, Vol 19, Pp 139-163 (2019)

Following wood pyrolysis, tar ball aerosols were laboratory generated from wood tar separated into polar and nonpolar phases. Chemical information of fresh tar balls was obtained from a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF
