Abstract
An investigation device includes a time of flight mass spectrometer with an entrance opening, and an electrically conductive tip on a cantilever which is movable from a first position near a sample on a sample holder to a second position near the entrance opening. A sample particle is obtained with the tip being in the first position from the sample. The tip, with the particle, is moved into the second position where the particle can be accelerated towards the entrance opening. The particle is analyzable by the time of flight mass spectrometer.
