3-D Manipulator for Mass Spectrometer

Small mass-spectrometer specimens are positioned in three dimensions by manipulator that employs two bellows to provide vacuum seal and accommodate movement of specimen holder. Inner bellows and outer bellows accommodate vertical and horizontal motion, respectively. Y-axis movement is in and out of plane of page. Specimen-holder column is hollow so electrical wires can pass through it to specimen.
