CHEM2712 Analytical Separations

This topic introduces the various modes of separation used in Chemistry. Areas of study include sample preparation, solid-phase and liquid-liquid extraction, chromatography, electrophoresis and microfluidics. A considerable focus will be on the mechanisms of separation, analytical performance and utility of each technique along with instrumentation and sample requirements.

This topic aims to introduce students to the various commonly used chemical separation methods. Specifically, this topic aims to give students:

• An understanding of the various separation mechanisms used by chemists
• An in-depth understanding of the thermodynamic and kinetic theory of separations
• The ability to explain the various modes of band broadening in chromatography and electrophoresis
• The ability to assess the quality of separations
• A comprehensive knowledge of the instrumental requirements of each separation technique
• Hands-on training in the use of a range of separation instruments to analyse and/or quantify a range of substances within a guided laboratory setting (including various sample extraction methods, GC, HPLC, ion chromatography and electrophoresis)
• Further training in the preparation of written reports
• An opportunity to work individually or as part of a team in order to investigate a range of analytical problems
