Abstract

The work is devoted to the analysis of materials based on a model adaptive composite of different compositions. The possibilities of mass spectrometry with visualization are demonstrated in order to study the surface of materials, including side cuts. Two-dimensional diagrams of ion distribution over the studied surfaces are constructed. The developed technique made it possible to detect both organic and inorganic components of model composites. The presented method for visualizing mass spectrometric data with laser desorption/ionization allows for the analysis of the surface of composite materials, the assessment of their exposure to aggressive environments, and the acquisition of important information about the surface structure and the distribution of compounds throughout the thickness of the sample, demonstrating the uniqueness of the proposed approach.
