    摘要: A mass spectometer for analyzing a beam of ions generated from a sample of analyze comprises an analyzer (3) and an interface between the analyze sample (1) and the analyzer. The inlet aperture to the analyzer (13) is positioned off the axis of the ion beam (2) exiting the interface system, and a deflector is (14) provided to generate an electric field between the interface system and the analyzer to deflect the ion beam into the inlet aperture of the analyzer.

    摘要: In a mass spectrometer, suitable for use in the determination of isotope ratios, having as a mass selector a sector magnet and detector means for detecting and measuring the intensity of ion beams at two or more positions in the focal plane of said sector magnet, the improvement comprises providing the exit (and optionally also the entrance) pole face of said sector magnet with a curvature such that the focal plane of said sector magnet lies substantially at right angles to the ion optical axis as it passes through said focal plane. With this arrangement, motion of detector means between positions in said focal plane by means of mechanical linkages controlled from outside the vacuum system of the mass spectrometer is facilitated.
