· The discovery of a mass-independent isotopic composition (Δ17O = (δ17O − 0.512 * δ18O) ≠ 0) in aerosol sulfate and the identification of its origin (aqueous-phase oxidation by O3 and H2O2) have renewed interest in measuring the oxygen isotopic content of sulfate. In this paper, we present a new method to measure both δ17O and δ18O in
