A method for the chemical analysis of molecules bound and bonded to solid surfaces is presented. The method includes the steps desorbing absorbate molecules or structurally significant fragments of these molecules by selective cleavage of a bond in an absorbate/substrate system using resonant excitation processes and detection of the absorbate species or its characteristic fragments using mass spectrometry techniques.

Abstract:
In a mass spectroscopy method, a primary beam of energetic particles is irradiated onto a target surface containing a sample in which the sample is a collection of analyte molecules contained in a matrix forming compound. When it is required to eject positive analyte ions the matrix forming compound can be a proton donor. When it is required to eject a negative analyte ion, the matrix forming compound can be a proton acceptor.

Abstract:
The present invention is directed to method and means for converting an energetic radiation image into an accelerated electron image, impacting the accelerated electron image onto an anode target to create both a charge image an a visible light image, producing signals representative of at least one of the two spatial coordinates of the electrons on the target and transmitting the visible light image for viewing.
