AP LDI coupled to an Orbitrap-based mass spectrometer is a useful tool to study organic substances and their degradation products in OLEDs without sample preparation or addition of matrix. New and aged OLEDs show significantly different intensities of specific ions deriving from the organic compounds or degradation products Mass Spectral Imaging (MSI) of OLEDs provides information about localization of ions underneath and/or beside the electrodes. MSI may allow detecting differential transitions in electrode locations with electrical defects Mass spectral behavior of degradation products of the electron blocker NPB requires further investigation (M+.(aged OLEDs) vs. „[M-H]+“(new OLEDs)
