Abstract

Detection of sulfur dioxide and sulfuric acid at high relative humidity was studied using a chemical ionization mass spectrometer (CIMS). The reactant ions used in the experiments are CO₃^-·nH ₂O (n=0-5), which react with SO₂ to form SO ₅^-·nH₂O (n=0-2). H₂SO ₄ reacts with the precursor ions to form HSO₄^- (m/z=97amu) and H₂SO₄·CO₃^- (m/z=158amu). We report the first use of the latter ionization scheme to detect sulfuric acid. High RH affects the detection of SO₂ and H ₂SO₄ by forming clusters with the reactant and product ions, reducing sensitivity. Increasing the temperature breaks these clusters. For SO₂ at high RH, either SO₅^- (m/z=112amu) or SO₅^-·H₂O (m/z=130amu) can be used for SO₂ detection without a decrease in sensitivity. For H ₂SO₄ at high RH, it is preferred to detect the ion H ₂SO₄·CO₃^- because the background signal at 158amu is small, and a better sensitivity can be achieved.
