Slurry method column chromatography
WebbColumn 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. Sometimes these columns are several inches ... WebbThe slurry method provides a more uniform packed column that does not contain air bubbles, dry areas, and channels. For this method, the stationary phase is mixed with a …
