Topic description

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.

Educational aims

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
Expected learning outcomes
On completion of this topic you will be expected to be able to:

  1. Demonstrate understanding of various separation techniques available to chemists, including the underlying thermodynamic and kinetic theories and the ability to identify appropriate methods for the separation of substances from within different matrices
  2. Explain the various modes of band broadening and their impact on the quality of a separation
  3. Use mathematical methods to assess the performance of a separation
  4. Demonstrate understanding of the instrumental requirements of each technique
  5. Use the various separation techniques to analyse and characterise substances within a laboratory setting
  6. Prepare written reports
  7. Work individually or as part of a team in order to investigate a range of analytical problems

Key dates and timetable

(1), (2)

Each class is numbered in brackets.
Where more than one class is offered, students normally attend only one.

Classes are held weekly unless otherwise indicated.

FULL

If you are enrolled for this topic, but all classes for one of the activities (eg tutorials) are full,
contact your College Office for assistance. Full classes frequently occur near the start of semester.

Students may still enrol in topics with full classes as more places will be made available as needed.

If this padlock appears next to an activity name (eg Lecture), then class registration is closed for this activity.

Class registration normally closes at the end of week 2 of each semester.

Classes in a stream are grouped so that the same students attend all classes in that stream.
Registration in the stream will result in registration in all classes.
  Unless otherwise advised, classes are not held during semester breaks or on public holidays.
