  • Plasma jet device and method of operating same
    Patent number: 4147957
    Abstract: A plasma jet device which comprises first and second anode electrodes spaced apart and positioned such that their axes, if extended, would intersect at an angle, and a third cathode electrode positioned offset from the plane formed by the extended axes of the first and second electrodes, the plasma jet device forming an ionized column of gas having the shape of an inverted Y and providing a stabilized excitation zone.

  • Spectrometric system and cassette
    Patent number: 4049353
    Abstract: A spectrometric system for multielement analysis and a cassette for use in such system, the cassette having a plurality of aligned and nonaligned channels therethrough, each of which has an inlet and an outlet, the inlets in the focal plane of the spectrometer, and each outlet adjacent a photomultiplier tube, and optical transmission means within the cassette to transmit spectral emission radiation received by the nonaligned inlets through channels to the photomultiplier tubes adjacent the nonaligned outlets for such channels.

  • Plasma jet device and method of operating same
    Patent number: 4009413
    Abstract: A plasma jet device which comprises an anode electrode and a cathode electrode to provide an ionized gas column therebetween, the anode and cathode electrodes positioned such that their axes, if extended, would intersect at an angle, the ionized gas characterized by an inverted V form and a reaction zone in the region of intersection of the extended axes, and an external means to introduce a material to be observed directly into the reaction zone.
