WAVELENGTH DISPERSIVE XRF SYSTEM USING FOCUSING OPTIC FOR EXCITATION AND A FOCUSING MONOCHROMATOR FOR COLLECTION

摘要

X-ray fluorescence (XRF) spectroscopy systems and methods are provided. Onesystem (100) includes a source (110) of x-ray radiation and an excitationoptic (120) disposed between the x-ray radiation source (110) and the sample(130) for collecting x-ray radiation from the source and focusing the x-rayradiation to a focal point on the sample to incite at least one analyte in thesample to fluoresce. The system (100) further includes an x-ray fluorescencedetector (150) and a collection optic (140) comprising a doubly curveddiffracting optic disposed between the sample and the x-ray fluorescencedetector for collecting x-ray fluorescence from the focal point on the sampleand focusing the fluorescent x-rays towards the x-ray fluorescence detector.
