The Thermo Scientific ARGUS VI is a revolutionary static vacuum mass
spectrometer using state-of-the-art technology for the isotopic analysis of
small samples of the Noble gases, in particular, Argon. It has an extremely
robust design and excellent ion optics combined with industry-leading
instrument control software to create the total argon analysis package.
The ARGUS is a totally new approach to Noble gas mass spectrometry. It
comprises a magnetic sector analyzer with 13 cm, 90° extended geometry ion
optics giving an effective dispersion of 26 cm. The geometry combines superb
ion optic performance with two-direction focusing and high dispersion. The
analyzer incorporates novel design elements that have hitherto been unavailable
in static vacuum systems.
