Real time volatile sulfur compounds monitoring using DART ion source

(AMR)

Real-time MS acquisition is important for performance evaluation and degradation monitoring of All-solid-state S-Li batteries (ASLSBs).
ASLSBs are expected as next-generation batteries with high energy density. PTR-MS and GC-MS have been used to monitor volatile organic compounds not only volatile from battery but also various volatile. Volatile were measured by APCI-based ambient ionization, more than 100Da molecular weight volatile components were detected. This meant APCI-based ambient ionization is important to analyzing more detailed material analysis.
We will report on the DART ionization behavior of SO₂ and H₂S as basic research.
DART is suitable for the analysis of sulfur compounds that are easily oxidized in the atmosphere because DART yields very little nitrogen oxides.
