Module Aims
|
To introduce the student to the theory and practices of modern separation techniques.
To provide the necessary background to allow the student to select an appropriate separation technique for a given analysis.
To introduce the student to the application of chromatography in a wide range of environments e.g. industrial, medical, environmental.
|
Learning Outcomes
|
The student should be able to:
7 Understand the thermodynamic and molecular basis for equilibrium separation.
7 Calculate R', K 5, RS, R, N and H for a given separation.
7 Explain the individual and collective contributions to bond broadening and ways in which they can be minimised.
7 Describe the sample preparation, method development and instrumentation required for Gas Chromatography, Liquid Chromatography and Capillary Electrophoresis.

1. Chemical equilibria; activity, acid-base
titrations,
formation constants, solubility products potentiometric
titrations.
2. Thermodynamics of Separation - distribution coefficients,
chemical potential and conditions for equilibrium.
3. Molecular basis for equilibrium separation - the effect
of molecular structure on the distribution of a compound
between two phases. The empirical approach - Rohrschneider
constant.
4. Chromatography separation - definition and classification
of chromatographic mechanisms, scrption isotherms,
retention behaviour, distribution coefficient, capacity
factor, column selectivity, column efficiency, bond
broadening, diffusion, mass transfer, resolution,
quantitative methods.
5. Gas chromatography - principles, stationary phases and
instrumentation.
6. High performance liquid chromatography - principles
stationary and mobile phases and instrumentation.
7. Capillary electrophoresis - principles, mobile phases and
instrumentation.
8. Sample preparation - solid phase extraction and
derivatisation.
9. Chiral chromatography - stationary and mobile phases for
gas and liquid chromatography.
