Short summary
Ionization reagents suitable for accurate measurements of the atmospheric gas-phase amine vapour concentrations are needed. Based on computational results, acetone is a viable option for use as an ionization reagent in CI-APi-TOF measurements on atmospheric dimethylamine. However, comparison between the computational and experimental results revealed notable discrepancies. Further study is still required before the acetone CI-APi-TOF can be considered a viable option in practice.
