An x-ray fluorescence system and method of fabrication are provided which include a titanium x-ray source, a focusing, doubly-curved lithium fluoride (LiF) crystal optic, and a detector. The titanium x-ray source includes a titanium target on which electrons impinge to generate a diverging x-ray beam with a titanium-based characteristic energy, and the focusing, doubly-curved LiF crystal optic monochromates and focuses the diverging x-ray beam from the titanium x-ray source to provide a monochromated and focused x-ray excitation beam directed to impinge on a sample. The crystal optic and the titanium x-ray source operate at a Bragg angle which facilitates polarization within the x-ray fluorescence system. The detector receives fluorescence from the sample induced by the x-ray excitation beam impinging thereon, with the fluorescence is indicative of a concentration of at least one element in the sample.

Polarized, energy dispersive x-ray fluorescence system and method

A sample handling apparatus/technique/method for a material analyze including a sample carrier for presenting a pressurized sample (e.g., LPG) to a sample focal area of the analyzer; a removable fixture for charging the pressurized sample into the sample carrier; the removable fixture including at least one port to provide sample to and from the fixture and carrier. The sample handling apparatus may include a retainer, wherein the sample carrier is removeably combined with the fixture using the retainer, the apparatus being insertable into the analyzer for sample analysis; and wherein the retainer includes an aperture for presenting the sample to the focal area from a filmed, lower end of the carrier in proximity therewith.
