  • Publication number: 20140056782
    Abstract: Devices for the preparation of a plurality of samples on mass-spectrometric sample supports are presented, where the samples are prepared by the application of liquids such that they are suitable for ionization in a mass spectrometer, for example ionization by matrix-assisted laser desorption (MALDI). The invention proposes that the dispenser and sample sites are positioned with respect to each other by means of two rotations about two eccentric axes. As acids and aggressive solvents are used, which have to evaporate on the samples, the preparation can be carried out in a closed chamber with air circulation, filter, dispenser and mounting table for the sample support. The drives for positioning the dispenser and sample support relative to each other are preferably kept outside the chamber because the aggressive vapors would very quickly damage the motors and also the complex cross-rails of the XY translation stages used to move the sample supports.
