MS spectra of DMS oxidation at the air–water interface oxidation by applying heavy water (H2 18O) as a microdroplet generation source. (A) DMS oxidation products detected in MS positive ion mode, MS range 75–85. (B) DMS oxidation products detected in MS negative ion mode, MS range 50–130. (C) MS range 110–120, magnified by 7 times from panel (B). (D) MS range 60–70, magnified by 4 times from panel (B). (E) MS range 78–88, magnified by 8 times from panel (B). (F) MS range 92–102.
