(Example collection in progress) What is sublimation refining? │ Removal of impurities from high-precision materials, achieving high purity.
Please use it for the removal of residual solvents and the purification of materials that are difficult to dissolve in organic solvents! It has a proven track record in organic semiconductors and organic EL (OLED).
"Sublimation purification" refers to a method of purification that utilizes the temperature difference between sublimation and accumulation of a substance. In the case of vacuum deposition of organic EL materials, sublimation purification is generally performed to remove metal impurities and residual solvents that contaminate the vacuum level. Additionally, when the target substance is poorly soluble in organic solvents and cannot be purified using methods such as column chromatography or recrystallization, sublimation purification is employed to remove impurities and solvents, increase purity, separate components, and reduce metal content.
basic information
We analyze the material to be purified before sublimation in advance to derive the optimal sublimation conditions. By purifying under optimal conditions, it becomes possible to obtain the target substance with high yield and high purity. Additionally, we can perform product analysis after purification using equipment such as LC, LC-MS, GC, GC-MS, TG, and ICP-MS in-house.
