ABSTRACT:
A mass spectrometric analysis of the content of surfaces, it is necessary to bring the analyte molecules into the gas phase. This is done with a tightly focused, preferably pulsed laser beam. This laser beam is focused onto the surface with a mirror that is placed as close as possible to the analysed surface. In order to achieve a very small focal point, deflection and focusing of the laser beam is done with a single optical element. The evaporated material passes through a opening in the mirror into the mass spectrometer. It is also possible to let the evaporated material pass right next to the mirror into the mass spectrometer.
