Description

technical field [0001] The invention relates to the technical field of element detection, in particular to a built-in neutron element analysis device. Background technique [0002] Facing the current demands of industrialization, and aiming at problems such as environmental pollution and resource waste, it is necessary to grasp the content information of industrial materials, so as to realize the classification and use of industrial materials and optimize the guidance of production. At present, most industrial material factories analyze the composition content of industrial materials through laboratory chemical detection methods, including ICP-MS, flame atomic spectrometry, ion chromatography, etc. The above method requires sample preparation, takes a long time for detection and analysis, and cannot obtain real-time material composition information, and the detection samples are usually obtained by sampling methods, which are greatly affected by human factors. [0003] At t...
