The chemical species formed on the ELT caused by the electrode deposition are analyzed by liquid extraction surface analysis (LESA) nano ESI-Orbitrap MS. N-oxygenated and N-hydrogenated molecules of 8-hydroxyquinoline and Alq3 with a wide range of N values and generation of several decomposition components on TPBi are detected and characterized.
