Gravity chromatography is appropriate for laboratory scale and involves minimal instrumentation. It relies primarily on hand-packed columns and is particularly well suited for single-step purifications like desalting and affinity applications. This section provides an overview of gravity chromatography and selection ... 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… ez backsplash
