Silica for Dry Column Chromatography (DCC) is a fast, easy, and efficient method for separating and/or purifying industrial quantities of compounds. DCC links analytical thin layer chromatography (TLC) with preparative column chromatography (CC). Like TLC, DCC is a "non-elution" method utilizing Nylon Foil Tubing as a support. In TLC solvent flow is by capillary action going against gravity whereas in DCC, solvent flow is by gravity. Like Column Chromatography, columns of most any size may be filled in DCC to separate or clean up very large quantities of materials. Silica Gel for DCC consists of a UV254 fluorescent indicator and a silica gel with a porosity of 60A, particle distribution of 63-200um, and a quantity of 500g.
