    摘要: A process for producing mass filters for use in mass spectrometers. Several electrodes having precisely shaped surfaces must be held in precisely determined positions with respect to each other. Insulators are placed into position on the surface of a mandrel and a layer of metal is deposited over the mandrel and insulators to form a composite unitary structure, including the electrodes. The deposited metal overlying the insulators is then removed, electrically isolating the electrodes.
