Pre-requisite None
Co-requisite None
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.

Indicative Syllabus
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.
