Method and apparatus to the upper surfaces desorption ionization by charged particles

摘要

A device and a method for producing analyte ions from a sample. It is an ion generating in front of the direction is provided, which is a chamber with an outlet and a surface, which comprises a material, and a means for applying a high speed gas flow through the chamber to the outlet, in such a way that charged particles by a physical interaction between the high speed gas and the material to be produced. The charged particles then cause the generation of primary ions by an interaction with molecules of the high speed gas. The primary ions, from the outlet of the ions generate in front of the direction of a sample support surface and emitted toward the ends of the analyte ions are produced by an impact of the primary ions on the analyte sample at the surface.
