Column purification｜Fukui Canon Materials

Column purification is a method in which a cylindrical container, or column, is filled with a packing material possessing various physicochemical properties, and the substance to be purified is dissolved in a solvent and poured into the column. Separation and purification are achieved by utilizing the difference in affinity between the packing material and the solvent passed through it, as well as the difference in molecular size.

Fukui Canon Materials' Column Purification Technology

We have a range of columns supporting different scales of production. This enables seamless process development from laboratory scale through to mass production, with early-stage consideration of optimal large-scale production conditions. Leveraging our years of expertise in purification, concentration, and synthesis, we recover high-purity materials from raw materials containing multiple impurities by using optimally formulated conditions.
