ABSTRACT:
An electrode for influencing ion motion in mass spectrometers, having a dielectric substrate and a conducting layer on portions of the substrate, wherein peripheral borders, edges or convex shapes of the conducting layer adjoin free regions of the substrate. According to the invention, a dielectric layer is provided on transitions from the conducting layer to the adjoining free regions of the substrate such that at least some of the peripheral borders, edges or convex shapes of the conducting layer are covered.
