Explaining the purification techniques for impurity removal, "Column Purification / Sublimation Purification," in a case study collection.
We achieve improved product characteristics and stabilized quality through the removal of impurities in semiconductors and electronic materials. We are publishing examples of the purification of electronic materials such as semiconductors and perovskite solar cells.
In the development of semiconductors and electronic materials, have you ever experienced situations where "the calculations show no issues, but the characteristics are unstable" or "there is variability in the evaluation data"? One of the causes of this is trace impurities that remain in the materials. In particular, by-products that have a structure similar to the main component are difficult to separate through recrystallization or washing, which can prevent the material from exhibiting the desired characteristics. Our purification technology is one effective approach to address these challenges. We capture the behavior of impurities based on physical properties such as chemical structure, polarity, and interactions, and select appropriate separation methods. When selective separation using columns is difficult, we can also utilize temperature differences through sublimation to reduce impurities and residual solvents. We contribute to various fields, including semiconductor materials and organic EL materials, where high purity is required. If you are facing challenges in the purification process, please feel free to consult us. *You can view examples of column purification and sublimation purification from the "Catalog Download."
basic information
【Column Purification Technology】 This is a method of purification that involves packing a cylindrical container called a column with fillers that have various physicochemical properties, and then flowing the target substance dissolved in a solvent through it for purification. Separation and purification are carried out by utilizing the affinity between the filler and the solvent, as well as differences in molecular size. Our company leverages its extensive know-how to propose optimal formulations for recovering high-purity materials from raw materials containing multiple impurities, contributing to loss reduction and cost reduction. 【Sublimation Purification Technology】 This is a purification method that utilizes the temperature difference between sublimation and recondensation to remove impurities and residual solvents. It can be applied to materials that are difficult to dissolve in organic solvents or substances that are challenging to separate using column purification or recrystallization. It achieves high yield and high purity purification, contributing to the reduction of impurities in high-precision agents such as organic EL materials and semiconductor materials. *You can view examples of column purification and sublimation purification from the "Catalog Download."*
