摘要： 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 location on the sample and for determining the size of the spot produced on the sample. The analyzer may include a digital camera oriented toward the portion of the sample that is, or would be, interrogated by the x-ray spot to facilitate aiming the analyzer. The analyzer may generate a reticule in a displayed image to indicate the portion of the sample that is, or would be, illuminated by the x-ray beam. The analyzer may automatically annotate the image of the sample with text or graphics that contain information about the analyzed sample. The image may be stored in the hand -held analyzer or provided for external storage or display.

摘要： Techniques disclosed herein include systems and methods for identifying counterfeit gold jewelry and other counterfeit gold items. Techniques include determining—using a non-destructive mechanism—whether an item of interest (such as an article represented as true gold) is solid gold or a gold-plated object. Techniques include using an X-ray fluorescence (XRF) analyzer to differentiate true gold from gold plating. The XRF analyzer can distinguish between gold plating and bulk gold material by comparing a ratio of L-alpha and L-beta x-ray lines of gold. The analyzer measures a ratio of intensities of characteristic L-lines of gold using X-ray fluorescence (XRF) spectroscopy. When implemented using an XRF analyzer, the system nondestructively determines whether a test object is made of solid gold/gold alloy or has gold plating only.

摘要： An analyzer for analyzing a composition of a sample, and methods of operating an analyzer. The analyzer may include an optical illuminator and a Raman spectrometer to produce Raman spectral data representative of Raman radiation emitted from the sample in response to the illuminating light. Features to reduce background fluorescence are optionally provided. An x-ray illuminator may be provided to illuminate the sample with x-rays, and also an x-ray spectrometer may be present to produce x-ray spectral data representative of fluorescence radiation emitted from the sample in response to the illuminating x-rays. A processor receives the Raman spectral data and any x-ray spectral data and provides an analysis of a compound in the sample.
