WebJun 5, 2012 · Column chromatography is a commonly used purification technique in labs across the world. Done right it can simply and quickly isolate desired compounds from a mixture. But like many aspects of practical chemistry, the quick and efficient setting up and running of a column is something that can take years to master. The mobile phase or eluent is a solvent or a mixture of solvents used to move the compounds through the column. It is chosen so that the retention factor value of the compound of interest is roughly around 0.2 - 0.3 in order to minimize the time and the amount of eluent to run the chromatography. The eluent has also been chosen so that the different compounds can be separated effectively. Th…
WebColumn chromatography is another kind of liquid chromatography. It works just like TLC. The same stationary phase and the same mobile phase can be used. Instead of spreading a thin layer of the stationary phase on a plate, the solid is packed into a long, glass column either as a powder or a slurry.
