Application of Tapping-mode Scanning Probe Electrospray Ionization to Imaging Mass Spectrometry of Additives on PMMA Surface
Tapping-mode scanning probe electrospray ionization (t-SPESI) was applied to imaging mass spectrometry of oxidation inhibitor, Irganox1098 contained in a PMMA model film. The effectiveness of t-SPESI was demonstrated to detect sensitively UV degradation products and to obtain their imaging map.
