adsorbed by the charcoal. (iv) The air becomes dry in the presence of silica gel because the water molecules get adsorbed on the surface of the gel. It is clear from the above examples that solid surfaces can hold the gas or liquid molecules by virtue of adsorption. The process of removing an adsorbed substance from a surface on which it is

As you inject more and more samples, these contaminants build up on the top of the column and prevent the sample to properly adsorb and distribute. This results in a distortion of the peak profile. Often this problem is accompanied by an increase in back pressure. Q.: OK, that could be it.
