Sample ring dimensions: Φ 40 × 34 × 4.5mm, Φ 40 × 34 × 5mm, Φ 38 × 32 × 5mm, Φ 32 × 28 × 4mm, Φ 29.2 × 24 × 4mm, Φ 25.2 × 20 × 4mm, Φ 19.2 × 14 × 4mm (outer diameter × inner diameter × thickness)

Widely used as consumables for equipment such as infrared spectroscopy tablet press, XRF spectrometer with powder tablet press, and fully automatic powder tablet press.

In continuous production factories such as geological and mining laboratories, steel mills, electrolytic aluminum workshops, and cement plants, it is necessary to conduct physical and chemical analysis of products or production processes every day to ensure the quality of the produced products. After the introduction of self fluorescence and diffraction analysis methods into the above-mentioned industries, the analysis and detection of samples have become direct and simple, that is, after planar processing of the test samples, fluorescence and diffraction can be directly obtained to obtain analysis results.

In traditional sample production, the selected samples need to be crushed and compressed into flat test pieces under high pressure using a press machine. To maintain the integrity of the samples, boric acid edging is used. However, this type of sample takes a long time to produce and the texture of the samples is uneven, which can easily lead to boric acid contamination. In the long-term work of the research institute, it has been found that sample rings made of materials with good flexibility and elongation have high practical value for the production of test samples and the accuracy of test results.
