Paper Chromatography Is An Example Of Thin Layer Chromatography
Therefore it is obvious that chromatography is going to save a lot of time.
Paper chromatography is an example of thin layer chromatography. The paper selectively retains different components according to their differing partition in two phases. A huge advantage which is provided by thin layer chromatography is that it is responsible for saving a lot of time. On the other hand paper chromatography is responsible for taking numerous hours to develop the plate.
Thin layer chromatography is performed on a sheet of an inert substrate such as glass plastic or aluminium foil which is coated with a thin layer of adsorbent material usually silica gel aluminium oxide or cellulose. The stationary phase of the thin layer chromatography is the glass plates coated with silica gel. The stationary phase of paper chromatography is the water trapped in the cellulose filter paper.
Paper chromatography is a type of partition chormatography. This layer of adsorbent is known as the stationary phase. Solutes are separated according to their solubility in mobile phase or their attraction to the stationary phase depend in the polarity.
Phases in which substance will be separated. Chormatography paper contains water trapped in it which acts as the stationary phase. Two types of paper chromatography.
After the sample has been applied on the plate a solvent or solvent mixture is drawn up the plate via capillary action.
