The Thermo Scientific HELIX SFT static vacuum mass spectrometer is a state-ofthe- art magnetic sector mass spectrometer for the isotopic analysis of small samples of the Noble gases. It comprises a magnetic sector analyzer with 35 cm, 120-degree extended geometry ion optics.

The HELIX SFT system is capable of analyzing all the isotopes of the Noble gases but is in particular suited to the simultaneous collection of the two isotopes of helium at masses 3 and 4. The geometry combines excellent 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.

The Thermo Scientific HELIX MC static vacuum mass spectrometer is a state-of-the-art magnetic sector mass spectrometer for the high precision isotopic analysis of small samples of all of the Noble gases. It comprises a magnetic sector analyzer with 35 cm, 120-degree extended geometry ion optics. The geometry combines excellent ion optic performance with two-direction focusing and high dispersion.

This instrument represents the ultimate tool for the isotopic measurement of the Noble gases.

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.
