Abstract
Provided is an X-ray fluorescence analyzer capable of reducing consumption of a gas constituting a measurement atmosphere. The X-ray fluorescence analyzer is provided with a sample chamber configured to place a sample therein, a measurement chamber arranged adjacent to the sample in the sample chamber, an X-ray tube configured to irradiate the sample with X-rays, and a detector configured to detect the X-rays reflected by the sample. The detector is provided with a passage through which the X-rays reflected by the sample pass, the passage being positioned in the measurement chamber, and a hole connecting the passage and an outside of the detector.

An X-ray fluorescence analyzer comprising:
- a sample chamber configured to place a sample therein;
- a measurement chamber arranged adjacent to the sample in the sample chamber;
- an X-ray tube configured to irradiate the sample with X-rays;
- and
- a detector configured to detect X-rays reflected by the sample upon X-ray irradiation,
- wherein a collimator is provided at a tip end of the detector, the collimator comprising
- a window member,
- a passage, having a tip end at a sample chamber side of the passage and a back end at a window member side of the passage, through which passage the X-rays reflected by the sample pass, the passage being positioned in the measurement chamber;
- and
- a first hole, extending from a back end of the passage to an outside of the detector, connecting the passage to outside of the detector.
