The effect of H<sub>2</sub>SO<sub>4</sub> &ndash; amine clustering on chemical ionization mass spectrometry (CIMS) measurements of gas-phase sulfuric acid

The state-of-the art method for measuring atmospheric gas-phase sulfuric acid is chemical ionization mass spectrometry (CIMS) based on nitrate reagent ions. We have assessed the possible effect of the sulfuric acid molecules clustering with base molecules on CIMS measurements using computational che...
