PROBLEM TO BE SOLVED: To provide a sample holder, a sample chamber and an X-ray analyzer capable of preventing a sample from being exposed to air as much as possible.SOLUTION: A sample holder includes: a box part 12 in which a sample 5 is to be disposed; and a lid part 11 that moves in a lateral direction to open/close an opening of the box part 12. With the lid part 11 closing the opening, airtightness of the box part 12 is maintained. A sample stage 16 for placing a sheet-like sample 5 thereon is provided in the box part 12. The sample stage 16 moves up and down with the lid part 11 opening the opening. In a sample chamber of an X-ray analyzer, power is supplied to move the lid part 11 and the sample stage 16, and X-rays are radiated to the sample 5 from above to perform X-ray fluorescence analysis. The sample is disposed in the box part 12 in a decompressed atmosphere and the lid part 11 closes the opening, so that the sample 5 can be held in the sample holder, preventing air exposure. The lid part 11 opens the opening in the decompressed sample chamber, so that X-ray fluorescence analysis can be performed, preventing air exposure. |
