Short summary
Aerosol mass spectrometers (AMSs) are frequently applied in atmospheric aerosol research in connection with climate, environmental or health-related projects. The paper describes a new real-time technique for the measurement of organic peroxides, which play an important role in new particle formation and as reactive oxygen species in aerosol–health-related aspects of atmospheric aerosols.
