Selenium assay [Selenium grade detection]

Testing/Consultation (Wang Li)
Selenium is one of the scattered non-metals, and crude selenium is a by-product in the copper smelting process. The growth of selenium production has been relatively slow, and the annual supply is limited. Selenium has a wide range of uses and can be used in many fields such as metallurgy, glass, ceramics, electronics, solar feed, etc. With the development of the world economy and the emergence of new application fields, the downstream demand for selenium continues to grow, which to a certain extent has led to the price of selenium. Keep rising. However, as the price of selenium continues to rise, its downstream consumption structure will continue to adjust to adapt to price changes. The profit margin of traditional selenium products is expected to remain at a medium level, while the profit margin of high-end selenium products with higher technical thresholds is expected to be will remain at a high level.
