Description

Technical Field

[0001] The utility model belongs to the technical field of fluorescence analysis, and in particular relates to a raw material batching device. Background Art

[0002] Neutron activation is the most important method in activation analysis. It uses neutrons produced by reactors, accelerators or isotope neutron sources as bombardment particles. It is a qualitative and quantitative analysis method to determine the elemental composition of a substance. X-ray fluorescence analysis uses primary X-ray photons or other microscopic ions to excite atoms in the substance to be tested, causing them to produce fluorescence to analyze the composition of the substance and study its chemical state. According to the different excitation, dispersion and detection methods, it is divided into X-ray spectroscopy and X-ray energy spectrometry.

[0003] In the process of analyzing materials, whether it is neutron activation analysis or X-ray fluorescence analysis, the raw materials need to be batched first so that the uniformity of the raw materials reaches an appropriate standard.

The next batching can only be carried out after one batch is completed, and the batching barrels need to be manually supported for stability, which is inconvenient to operate. Therefore, we propose a raw material batching device. Utility Model Content
