CHROMATOGRAPHY
&
IT’S TYPES
1

2. CHROMATOGRAPHY
Chromatography is a technique that separates
components of a mixture
• The Russian botanist Mikhail Tsvet coined the term
chromatography in 1906.
• Archer Martin and Richard Synge during the 1940s and
1950s, established the principles and basic techniques
of partition chromatography, and their work
encouraged the rapid development of several
chromatographic methods

3. CHROMATOGRAPHIC TERMS
Adsorbent:
A material which will allow
components of the mixture
to adhere to itself
The common adsorbents
used are alumina (Al2O3)and
silica gel (SiO2). Both are
polar.
Adsorption is the process of
molecules 'adhering' to one
another, without the making
of chemical bonds.

4. PRINCIPLE OF
CHROMATOGRAPHY
The mixture is dissolved
in the mobile phase,
which carries it through
a structure holding
another material called
the stationary phase.
Components of
sample most
strongly adsorbed
Components of
sample least
strongly adsorbed
Eluent
STATIONARY
PHASE

5. Affinity ------ Adsorption & Solubility
High adsorption-------- slow movement through a column
High solubility----------- Faster movement through a column
Polarity of the compounds dictate their affinities towards Stationary & mobile
phase.

8. ADSORBTION CHROMATOGRAPHY
Separation of components
depends upon the degree of
adsorption by the adsorbent
and solubility in the solvent

9. PARTITION CHROMATOGRAPHY
Based on the partitioning of compounds
between a liquid stationary phase and a
liquid mobile phase. The liquid stationary
phase can be held on any solid support.
Based on solute partition between
two liquids
9

10. Based on the exchange of charged components of the
mixture with charges on stationary phase
• Allows separation of charged/ ions/ polar molecules
• Cation exchange= Column retains cation
• Anion exchange= Column retains anion
A change in pH affects the charge on the particular
molecules and therefore alter binding
ION EXCHANGE CHROMATOGRAPHY

11. CATION EXCHANGE CHROMATOGRAPHY
11
Positively charged molecules
replace cations attached to
negatively charged functional
groups

13. Affinity chromatography is a method of separating
biochemical mixture based on a highly specific
interaction between target molecule and ligand
attached to stationary phase.

14. GEL PERMEATION CHROMATOGRAPHY
The smaller analytes can
enter the pores more easily
and therefore are eluted last
Conversely, larger analytes
lesser time in the pores and
are eluted quickly.
The size of the pores for the
packing should be chosen
according to the range of
molecular weight of analytes
to be separated.
Separation of molecules on the basis of their size and shape
