TL;DR: In this paper, the authors present a simple way of estimating mass discrimination effects of a nitrate-based chemical ionization atmospheric pressure interface time-of-flight (CI-APi-TOF) mass spectrometer.

TL;DR: In this paper, the authors conducted field measurements at a rural site in central Germany in the proximity of three larger dairy farms to investigate whether there is a connection between NPF and the presence of amines and/or ammonia due to the local emissions from the farms.

TL;DR: It is shown that NOx suppresses particle growth in general, but the suppression is rather nonuniform and size dependent, which can be quantitatively explained by the shifted HOM volatility after adding NOx.

TL;DR: In this article, a new in situ optical method was deployed to detect the viscous state of α-pinene SOA particles and measured their transition from the amorphous highly viscous states to states of lower viscosity.

TL;DR: In this article, the authors compared the molecular composition of positive and negative HOM clusters measured with atmospheric pressure interface time-of-flight mass spectrometers at three different temperatures (25, 5, and − 25) ∘ C).
