  • Patent number: 4859848
    Abstract: An apparatus is provided for use in determining the components of an inputted gas mixture. The apparatus includes a single piece body or framework preferably made of a high insulating material, such as ceramic. The body includes a number of cut-outs for receiving or incorporating hardware used in generating ions, controlling their movement, and directing them to an ion collector plate. One of the cut-outs formed in the insulating body receives an ion source assembly. Another of the cutouts is a passageway with metallized material coated along the walls thereof for use in generating an electric field. A third cut-out receives and is associated with a magnet assembly used in directing ion movement towards the collector plate. The single body and cut-out construction reduces the number of individual parts, improves the assembly of such parts and reduces adjustment time associated with such parts.

  • Patent number: 4847493
    Abstract: Apparatus and method are provided for calibrating a mass spectrometer. The calibration hardware includes a relatively small, relatively low pressurized tank for containing calibration gas. The calibration gas tank is preferably located inside the same housing that contains the ion source assembly and the analyzing section of the mass spectrometer. Each of the calibration gas and sample gas, whose components are to be determined, communicates with its own associated valve. These two valves control the flow of a selected one of the sample gas and the calibration gas to the ion source assembly. The calibration gas valve has an extremely low leakage rate and can be controlled to permit the passage of very low flow rates of calibration gas, which can be of benefit in checking the linearity associated with the ion source assembly pressure. For each calibration procedure, very small amounts of calibration gas are utilized, in a range around 10.sup.-5 STD cc.
