ABSTRACT:
An apparatus for releasably gripping a sample plate for use with a mass spectrometer has been developed, the sample plate having substantially parallel faces and a peripheral surface. The apparatus comprises a planar member and first and second guiding structures. The second guiding structure comprises a biasing mechanism which when activiated, provides a force that forces the second guiding structure towards the peripheral surface of the sample plate such that the sample plate is retained by the apparatus. Utilization of the configuration reduces frictional point contact thus reduces localized stress point resulting in yielding the surface material thus in effect guarding both sample plate and first guiding means from galling and/or reducing any type of material removal when gripping a sample plate, or releasing a sample plate.
