Embodiment Construction

[0039] The specific implementation of the sample cup of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] See attached figure 1 , 2 , the sample cup includes a main ring body 1, which is divided into an upper end 2 and a lower end 3 when the main ring body 1 is placed vertically, and an annular lower stepped groove 4 is formed on the outer surface of the lower end 3 . A lower collar 5 is arranged on the lower stepped groove 4 , the height of the lower collar 5 is the same as that of the lower stepped groove 4 , and the lower collar 5 is in clearance fit with the lower stepped groove 4 .

[0041] The same structure as the lower end 3, the outer surface of the upper end 2 of the main ring body 1 also forms an annular upper stepped groove 6, the upper stepped shaft 6 has a clearance fit with the upper collar 7, and an annular flange 8 is formed between the upper stepped groove 6 and the lower stepped groove 4 , A sna...

Abstract

The invention relates to the technical field of heavy metal detection parts and discloses a specimen cup, comprising a main ring body, wherein an inner cup is disposed in the main ring body, is in a tapered shape having a large upper mouth and a small lower mouth, and has a height less than or equal to the height of the main ring body; the upper port or the lower port of the main ring body is configured to be covered with a transparent film. Inner cups of Different sizes are disposed in the specimen cup so that a specimen is located at the center of the bottom of the specimen cup when measured.

Description

technical field [0001] The invention relates to the technical field of heavy metal detection components, in particular to a sample cup. Background technique [0002] In the field of heavy metal detection, for example, when radioactive heavy metals are detected by EDXRF equipment, the sample to be tested should be placed in the radiation station of the EDXRF device, and the radiation is irradiated upwards from the station for detection. [0003] The sample to be tested is generally placed in the sample cup, and then placed in the irradiation station. The bottom of the sample cup is a transparent film through which rays can pass through the transparent film. The sample to be tested is irradiated and measured. The EDXRF equipment receives the reflected light of the sample and analyzes it to obtain The content value of each heavy metal element in the sample. [0004] Due to the diversity of sample types and shapes, some samples that are small and not easy to fix cannot be posit...
