Planar chromatography and column chromatography are types of chromatography used mainly in the identification of components into the mixture
of the analyte. The main difference between planar chromatography and column
chromatography is the shape of the stationary phase used in the procedure.
Planar Chromatography:
Planar chromatography is one type of chromatography technique
in which the stationary phase is flat or plane medium.
Example of Planar
chromatography: Thin
Layer chromatography, paper chromatography
The stationary Phase used in thin Layer Chromatography &
planar chromatography is Silica, aluminum Silicate on Aluminium plate or glass
plate. Different types of Filter Paper are used as per the requirement in Paper
chromatography.
Column Chromatography:
In column chromatography the stationary phase is packed or
coated into the column, Hence it is known as the column chromatography.
The column of the chromatography may be the packed column or
the capillary column depends on the requirement.
Normally in gas chromatography, capillary columns are used.
Example of column
chromatography: Gas
chromatography, High-performance Liquid chromatography, Liquid chromatography
As per the requirements and the types of chromatography
different types of stationary phases are used. Solid or liquid stationary phase
is used in the column chromatography as per the requirement.
The liquid stationary phase is coated on the solid support on
the column, the solid support of the column.
Ion Exchange resins are used as the stationary phase in Ion
exchange chromatography. Gels are used in Size exclusion chromatography;
Different types of ligands are used in Affinity chromatography.
