Short summary
We describe voltage scanning methodologies using a high-resolution time-of-flight chemical ionization mass spectrometer (HR-TOF-CIMS) with acetate reagent ions to control for clustering observed in the mass spectrum. Operational considerations related to atmospheric measurements of carboxylic acids using acetate chemical ionization are discussed.
