<p>An improved quadrupole electrode used in a mass spectrometer, etc., which comprises two pairs of electrodes (1, 2, 3, 4), the sections of whose mutually-facing surfaces are formed in the shape of a hyperbola or circle, and whose electrode bars are made of ceramic, and further whose surfaces are covered with layers (5) made of conductive metal. And its manufacturing method characterized in that such four electrodes are assembled at predetermined intervals. Since the electrode bars are mainly made of ceramic, the bars can be formed precisely, and the quadrupole electrode can be easily assembled without troublesome adjustment. Thus a quadrupole electrode can be manufactured with a good reproducibility at a low price. <IMAGE></p> |
