Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, specifically to an X-ray fluorescence spectrometer. Background Technology

[0002] X-ray fluorescence spectrometry (XRF spectrometry) is a rapid, non-destructive instrument primarily used for elemental and chemical analysis. It works by bombarding materials with high-energy X-rays or gamma rays, exciting secondary X-rays. The energy and wavelength of these secondary X-rays are related to the types and amounts of elements in the sample. By measuring the energy and intensity of these secondary X-rays, the types and amounts of various elements in the sample can be determined.

[0003] Chinese patent discloses an X-ray fluorescence spectrometer (authorization announcement number CN 215449068 U). This patented technology can be configured with a base, rollers, and support components. When the position of the X-ray fluorescence spectrometer needs to be moved, the support components can be detached from the base, allowing the X-ray fluorescence spectrometer to be moved directly. This reduces the possibility of damage to the X-ray fluorescence spectrometer when moving its position. However, the object to be detected cannot remain in a fixed state, and the object will shake, resulting in poor detection results. Furthermore, the detection components of this device are inconvenient to replace or repair.

[0004] Therefore, those skilled in the art have provided an X-ray fluorescence spectrometer to address the problems mentioned in the background section. Utility Model Content
