Description

Technical Field

[0001] This utility model relates to the field of X-ray fluorescence spectroscopy analysis technology, and in particular to a dual-element detection channel device for a fixed-channel wavelength dispersive X-ray fluorescence spectrometer. Background Technology

[0002] Currently, fixed-channel wavelength dispersive X-ray fluorescence spectrometers typically measure only one element per channel, as illustrated in the utility model patent with publication number CN204789410U. However, to minimize the optical path, the diameter of the dish itself cannot be too large, thus limiting the number of channels. Existing fixed-channel wavelength dispersive X-ray fluorescence spectrometers in China can only be configured with 10 fixed channels, thus only allowing the simultaneous detection of 10 elements. This limits the ability to simultaneously detect a larger number of elements, restricting the instrument's detection capabilities and applications. Ordinary double-bent crystal spectrometers, with the adjustment device located on the spectrometer itself, result in a larger spectrometer size and require the crystal size to be halved for operation. This negatively impacts the spectrometer's installation, counting rate, and efficiency. Utility Model Content

[0003] In view of this, this case mainly addresses the installation and efficiency issues of fixed-channel wavelength dispersive X-ray fluorescence spectrometers, and requires overcoming at least one of the aforementioned defects in the prior art.

[0004] This utility model provides a fully mirrored double-bend crystal spectrometer, including a hollow spectrometer housing as a diffraction light path generating device, a primary collimator installed on the spectrometer housing, n secondary collimator slits and crystal adjustment devices installed on the spectrometer housing, a detector installed on the rear side of the secondary collimator slits and crystal adjustment devices, and an elemental spectrometer crystal installed on the secondary collimator slits and crystal adjustment devices.

[0005] As described in the background of this patent, existing fixed-channel wavelength dispersive X-ray fluorescence spectrometers in China cannot simultaneously detect a greater number of elements, thus limiting the instrument's detection capabilities and application. Ordinary double-bent crystal spectrometers require adjustment devices on the spectrometer itself, resulting in a large spectrometer size and halving the crystal size for usability. This negatively impacts the spectrometer's installation, counting rate, and efficiency. In contrast, this invention discloses a fully mirrored double-bent crystal spectrometer. By placing the spectroscopic crystal on a dual-slit and crystal adjustment device, and by incorporating multiple dual-slits and crystal adjustment devices within the diffraction path generator, it improves efficiency, counting rate, and facilitates convenient adjustment and installation.

[0006] In addition, the all-mirror double-bend crystal beam splitter disclosed in this utility model also has the following additional technical features:

[0007] Furthermore, n is greater than or equal to 2.

[0008] Furthermore, the elemental spectroscopic crystals installed on different dual-slit and crystal adjustment devices are spectroscopic crystals for different elements to be measured.

[0009] Furthermore, the secondary collimator and crystal adjustment device includes a hollow support, an exit slit disposed at the rear end of the support, a secondary collimator disposed inside the support and in front of the exit slit, the beam-splitting crystal located at the front end of the support, an adjustment handle connected to the beam-splitting crystal and disposed inside the support, an elastic component interacting with the adjustment handle, and an adjustment component interacting with the adjustment handle. The secondary collimator can also be replaced by the hollow structure of the beam splitter, which can also achieve the function of correcting the optical path.

[0010] Furthermore, the adjustment handle is mounted on the support via a rotating shaft, the spectroscopic crystal is mounted at the front end of the support, the elastic component is mounted at the rear end of the support, the adjustment component and the elastic component are located on opposite sides of the support, and the spectroscopic crystal and the elastic component are located on opposite sides of the rotating shaft.

[0011] Furthermore, the elastic component is a spring, and the adjusting component is an adjusting screw.

[0012] Furthermore, the spectroscopic crystal is a bent crystal, which is an essential component in this field.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
