WebThe mobile phase travels up the plate by capillary forces and sample components migrate varying distances based on their differential affinities for the stationary and mobile phases. When the solvent reaches the top of the plate, the plate is removed from the developing chamber and dried. WebColumns may be safely stored for short periods in most mobile phases. However, to protect equipment, it is desirable to remove salts from the instrument and column by purging the column with the same mobile phase without the buffer (for example, using 60/40 ACN/H 2 O to remove a 60/40 ACN/0.02 M phosphate buffered mobile phase).
