Abstract
A laser activated mass spectrometer having a sample holder for holding a given component to be investigated, a laser source for producing a laser beam to evaporate the given component and a vacuum chamber in which the evaporated component is analyzed, has the sample holder and the given component mounted outside the vacuum chamber of the mass spectrometer under atmospheric pressure or in an inert gas atmosphere. The sample holder comprises a polymer carrier film for depositing the component thereon with the carrier film forming part of a wall of the vacuum chamber of the mass spectrometer. The laser beam is directed onto the deposited component for evaporating the given component and simultaneously forming a hole in the carrier film through which the given component is transferred into the vacuum chamber of the mass spectrometer simultaneously with evaporation.
