Module aims

Analytical measurements are essential to everyday life, required to determine the composition and control the quality of many products, to protect the environment and to monitor health. Consequently Analytical Chemistry has a major impact, not only in chemistry, but also in fields such as biochemistry, and the forensic, food, environmental and pharmaceutical sciences. Forensic chemistry is the application of analytical chemistry to the law and involves the examination of physical traces, such as body fluids, bones, fibres, drugs and environmental contamination. Success in analytical chemistry requires the ability to make rigorous measurements, an appreciation of the principles and practice of modern instrumentation, and a problem-solving approach. This course aims to develop these skills, with an emphasis on the use of coupled chromatography-mass spectrometry techniques, a powerful combination with applications in the analysis of complex mixtures relevant to forensic, environmental and biological systems. Workshops will give you experience of research instrumentation applied to real-life problems. External lecturers will provide examples of applications in relation to forensics, drugs in sport, and the pharmaceutical industry.

Module learning outcomes

On completion of this module students will be able to:

  • Appreciate the breadth and diversity of analytical science.
  • Select appropriate methods for specific questions, by understanding how molecules interact with each other and their environment.
  • Recognise the importance of QA in analytical laboratories.

Module content

Multidimensional chromatography with mass selective detection

  • General principles and environmental and forensic applications of linear and orthogonal chromatographic hyphenation (including GC-GC and LC-GC).
  • Coupling chromatography to MS: experiment & theory.
  • Advanced mass spectrometry for atmospheric chemistry.

Module feedback

Individual feedback on performance on the continuous assessment is provided within 4 weeks, as per university guidelines. The closed examinations are marked typically within 10 days with mark slips (with per-question break-down) being returned to students via supervisors. Outline answers are made available via the Chemistry web pages when the students receive their marks, so that they can assess their own detailed progress/achievement. The examiners reports for each question are made available to the students via the Chemistry web pages.
