Abstract
A portable measurement apparatus is presented for inducing and measuring fluorescent X-ray radiation. It comprises an X-ray source (303, 902, 1005, 1105) adapted to controllably irradiate a sample (301, 803) with X-rays, and a detector (305, 406, 1006, 1106) adapted to detect fluorescent radiation emitted by said sample (301, 803). The X-ray source (303, 902, 1005, 1105) is an X-ray tube, an anode of which comprises at least one of silver, rhodium and molybdenium. Consequently said X-ray tube is adapted to controllably emit L-line radiation of at least one of silver, rhodium and molybdenium.
Claims23
A measurement apparatus for inducing and measuring X-ray radiation, comprising:
- an X-ray tube adapted to controllably irradiate a sample with X-rays,
- a detector adapted to detect radiation from said sample,
- a measurement head defining a sample receiving surface,
- next to said sample receiving surface, support structures defining a space for a removable separate enclosure, and
- a gas-filled separate enclosure removably fitted into said measurement head between the detector and said sample receiving surface,
- wherein the measurement apparatus is a portable measurement apparatus adapted to induce and measure fluorescent X-ray radiation, and wherein said X-ray tube comprises an anode which comprises at least one of silver, rhodium and molybdenum, and wherein said X-ray tube is adapted to controllably emit L-line radiation of at least one of silver, rhodium and molybdenum.
An interface cassette for setting up an interface between parts in an X-ray fluorescence measurement apparatus, comprising:
- a body part, which defines a cavity therein and an outside form for removably attaching the interface cassette to the X-ray fluorescence measurement apparatus,
- a sample side window between said cavity and the outside of the interface cassette and
- a detector side window between said cavity and the outside of the interface cassette, wherein said sample side window and said detector side window are permeable to X-rays.
