Description

Technical Field

[0001] The utility model relates to the field of grinding and polishing in chemical composition analysis, in particular to a grinding and polishing device for rod-shaped samples of a glow discharge mass spectrometer. Background Art

[0002] Chemical composition analysis of materials is an important test content in physical and chemical inspection. Glow discharge mass spectrometry is the most effective method for trace element detection. It has the advantages of direct solid sampling, full element analysis, fast detection speed, wide detection range, weak matrix effect, stable ion source, and excellent gas element analysis capabilities. It is widely used in various industries such as pure metals, alloys, ceramics and coatings. It has an irreplaceable position in the fields of high-purity metals and semiconductors, and provides an important basis for the selection of raw materials for application products in various fields.

[0003] In practical applications, glow discharge mass spectrometers can test a variety of sample forms. Depending on the characteristics of the reaction cell, the samples to be tested must be prepared into rod-shaped or sheet-shaped samples. Rod-shaped samples are more commonly used in routine testing because they are superior to sheet-shaped samples in terms of both stability and sensitivity.

[0004] Glow discharge mass spectrometry, based on the principle of glow discharge mass spectrometry, sputters and peels the sample surface layer by layer, which poses the following problems: Sample surface contamination and surface roughness significantly affect test results; Different sample processing methods, the cleanliness of the cutting heads and grinding discs used in processing, and thermal friction can further contaminate the sample surface, leading to test deviations. For example, elements prone to contamination include calcium and magnesium, and oxygen is tested for easily oxidized metals; alloy samples cannot be pickled due to their complex main components and can only be ultrasonically pretreated, which still cannot remove contamination. In summary, before testing, the sample to be tested needs to be cool-polished on different sandpaper or sanding belts to obtain a fresh sample surface. However, rod-shaped samples are small in size, with a diameter of less than 3mm, making them difficult to polish manually. There is also a risk of the sample flying out and injuring people or being lost. Utility Model Content
