  • Patent number: 4634867
    Abstract: The introduction of a sample into a mass spectrometer providing in one aspect a method which comprises placing the sample in a tube (16) open at only one end, placing around the tube (16) an O-ring (30), placing the sample tube (16) with its open end adjacent an aperture (12) of the inlet system of the mass spectrometer and compressing the O-ring (3) about the tube whereby to seal sample tube (16) against the aperture (12), the sample tube upon evacuation by the inlet system of the mass spectrometer forming part of the vacuum retaining wall. The invention also relates to a sample tube surrounded by an O-ring and preferably containing a boat for receiving the sample.

  • Patent number: 4634865
    Abstract: Magazine for introducing samples into the inlet system of a mass spectrometer. The magazine (22) comprises a flat plate having upper and lower surfaces which are generally horizontal during use. A zig-zag groove (32) is formed in the lower surface engageable by a reciprocable pin (34) to advance the magazine (22) by increments relative to an aperture (12) of the inlet system (10) of the mass spectrometer and recesses (24) are formed in the upper surface of the magazine for receiving tubes (16) containing samples for analysis. The recesses (24) extend transversely to the direction of movement of the magazine (22) and are arranged at a regular pitch equal to that of the groove (32) in the lower surface.

  • Patent number: 4634866
    Abstract: A feed system for picking a sample tube off a magazine and introducing the sample tube into the inlet system of a mass spectrometer. The feed system comprises a pick-up tube (52) designed at its forward end to fit over a sample tube (16) resting on the magazine (22) and grip the sample tube (16). A carriage (40) supports the pick-up tube in a horizontal attitude and is driven towards and away from the inlet system (10) of the mass spectrometer by means of a motor driven pinion (46) engaging a rack (44) on the upper surface of the carriage (40). A cam track (50) raises the pick-up tube (52) after a sample tube (16) has been gripped to the level of the aperture (12) of the inlet system (10).

  • Patent number: 4205956
    Abstract: A sensitive portable detector for nickel carbonyl is provided which relies on chemiluminescence produced in the presence of ozone and carbon monoxide by pulse-modulating the carbon monoxide feed to the reactor chamber and detecting the resulting modulation of the output signal. The instrument is thus made insensitive to any NO which may be present in the gas sample.
