Analytical methods of identifying the composition of matter underpin all of modern science. Developments in analytical methodology open up new avenues for research, but also have direct and immediate societal impacts (e.g. screening for disease, detection of explosives). A good working knowledge of the range of analytical methods that are used widely in scientific research together with a critical understanding of the application of analytical methods in societal contexts are cornerstones of the Natural Sciences. The module will focus on three areas of analytical science, namely, Interaction of radiation with matter (uv-visible, infrared ad Raman spectroscopy/imaging), X-ray fluorescence, and mass spectrometry (including isotope ratio MS) that play key roles in the modern world. They deliver practical and sustainable innovations to enable significant advancements in areas such as healthcare delivery, life sciences, environmental management, energy, security, criminal justice, food safety, and water quality.
