Abstract
The interference of water vapor on the chemical ionization (CI) of hydroxyl radicals (OH) by sulfur hexafluoride ion (SF6-) was investigated using a flow tube system coupled to a high-pressure CI mass spectrometer. Water vapor, which is required to study heterogeneous reactions of OH under real tropospheric conditions, transforms the reagent ion SF6- into SF4O-and F-(HF)n, resulting in a substantial loss in CI sensitivity. Therefore, under humid conditions, peaks corresponding to OH are drastically diminished, while those corresponding to OH-water complex ions ([OH(H2O)n]-) are enhanced. [OH(H2O)3]- was observed as the major OH species. The obsercation of [OH(H2O)n]- by isolating humid conditions to the CI region and preliminary ab initio calculations suggested that [OH(H2O)n]- ions were produced from reactions between OH ions (OH-) and water molecules. An additional helium buffer flow introduced into the CI region reduced loss of the reagent ion and resulted in a partial recovery of OH peak intensities under humid conditions.
