7916834 Small spot X-ray fluorescence (XRF) analyzer March 29, 2011
A hand-held, self-contained x-ray fluorescence (XRF) analyzer produces a small x-ray spot on a sample to interrogate the elemental composition of a sample region of millimeter-size characteristic dimension. The analyzer includes a collimator for aiming an x-ray beam toward a desired loca
7899153 Automated x-ray fluorescence analysis March 1, 2011
A method for classifying a sample based upon a complete spectral analysis. The sample is illuminated with penetrating radiation and an initial complete spectral analysis is performed based on spectral resolution of resonant fluorescence lines emitted at the surface, or within the volume,
7875847 Docking stand for analytical instrument January 25, 2011
An analytical instrument may be docked in a stand. The stand provides electrical power, cooling, gas to purge air from an analytical gap within the instrument and/or other supplies or services to the instrument. The stand contains a contactless memory, such as an RF-ID tag, which stores
7821634 Laser-triggered plasma apparatus for atomic emission spectroscopy October 26, 2010
Multiple energy sources, such as a laser and electrical current, are employed, in close coordination, spatially and temporally, to clean a sample, vaporize its material and excite vapor atoms for the purpose of atomic emission spectroscopy. These methods permit better monitoring and
7787589 In vivo measurement of trace elements in bone by x-ray fluorescence August 31, 2010
Methods for in vivo measurement of lead or other trace elements in bone by x-ray fluorescence (XRF) without independent measurement of underlying tissue thickness are disclosed. In one method, the lead concentration is calculated based on the intensity of a first characteristic fluoresce
7702067 Measurement of lead by X-ray fluorescence April 20, 2010
A method, instrument, and computer program software product for characterizing a sample with respect to the presence of a specified element, either as a constituent of a surface layer or of the bulk of the sample. Intensities of fluorescent emission at two characteristic emission lin
7657003 X-ray tube with enhanced small spot cathode and methods for manufacture thereof February 2, 2010
An x-ray source produces a well-defined electron beam, without an undesirable halo. The x-ray source includes a housing, a cathode disposed within the housing, an anode spaced apart from the cathode for accelerating electrons emitted from the cathode and an x-ray emitter target dispo
7634052 Two-stage x-ray concentrator December 15, 2009
A method for obtaining a concentrated, monochromatic x-ray beam from a standard x-ray tube or other source of polychromatic emission. X-rays from the anode of the x-ray tube fluoresce an adjoining, independent target that produces a monochromatic spectrum, a portion of which is focus
7623614 Apparatus for inspecting objects using coded beam November 24, 2009
An apparatus for inspecting objects utilizes a fan beam or flood beam to illuminate the inspected region of the object. A modulator, which may take the form of a movable mask, dynamically encodes the beam so that each segment of the inspected region receives varying amounts of radiat
