Chromatographic paper

• For chromatographic analysis, three properties of the paper are important.

a) Rate of the flow of the mobile phase:

• Preference is given to slower paper.

b) Capacity of the paper and its mechanical strength:

• Ability to soak up a larger amount of solvent i.e. with greater thickness and fiber density.

c) Presence of trace impurities:

• May cause an affect on the detection or bind the substance chromatographed.
