Introductory description
n/a.
Module aims
This Core module focuses on theoretical and practical aspects of instrumental analytical techniques, including data generation, acquisition, processing, and interpretation, instrumentation and state-of-the-art applications. A range of techniques will be considered with emphasis being placed on chromatography, mass spectrometry, and nuclear magnetic resonance spectroscopy.
Techniques covered in lectures are reinforced in laboratory and workshop sessions.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Chromatography
- Chromatography theory
- Gas chromatography principles and practice
- Liquid chromatography principles and practice including thin layer chromatography, colum chromatography and high performance liquid chromatography (HPLC), including normal phase, reverse phase, and chiral chromatography. Hyphenated techniques including chromatography
Mass Spectrometry
- Basic terminology and concepts, including measures of performance
- Methods of producing ionized samples for mass spectrometry including: electron ionization (EI), matrix-assisted laser desorption/ionization (MALDI), electrospray ionization (ESI), and atmospheric pressure photoionization (APPI)
- Different types of analyzers including: time-of-flight, quadrupole mass analyser, Fourier transform ion cyclotron resonance, and Orbitrap
- Tandem mass spectrometry (MS/MS) techniques, such as collision-induced dissociation (CID)
- Analysis of mass spectra, including calculating masses using charge states or isotopic distributions; use of online protein databases
- Advanced data visualization methods, such as Kendrick mass defect plots
- Hyphenated techniques such as GC-MS or LC-MS
- Quantitation of analytes
- Proteomics
- Polymer analysis
Nuclear magnetic resonance spectroscopy
- Theoretical concepts of NMR including energy levels, magnetisation, radio frequency pulses, role of nuclear spin.
- Principles of continuous wave NMR and of Fourier Transform NMR including magnetisation, effect of RF pulse, physical basis of relaxation, NMR timescales, NMR lifetimes, nature of T1 and T2, line-widths, anisotropy.
- Consideration of NMR active nuclei including quadrupolar nuclei
- Solid-state NMR
- Introduction to EPR
Advanced NMR techniques and their applications: - 2D NMR: Including COSY, TOCSY, NOESY
- Polarisation transfer
- Carbon NMR
- A selection of other NMR techniques
Laboratory/workshop
Students will undertake a number of data handling and analysis laboratory workshops. Practicals will involve data acquisition (MRI, MS, NMR, Chromatography, IR, UV and elemental analysis techniques), with emphasis on high quality data collection and interpretation. Students will also undertake a project to determine the identity of an unknown compound. They will choose which techniques are most appropriate to use, process data using proprietary software all within a given financial budget and provide a written report on the analysis.
Learning outcomes
By the end of the module, students should be able to:
- Subject knowledge and understanding: Show an understanding of the fundamental principles behind analytical and spectroscopic methods and functions of various components in complex spectroscopic instrumentation; Appreciate Instrument performance characteristics; Demonstrate ability to process outputs from analytical instruments into interpretable datasets; Demonstrate the ability to evaluate and interpret data from a variety of measurements; Display consideration for sources and treatment of experimental error
- Key Skills: Demonstrate numeracy; Independently use information technology: databases, data-processing and other software.
- Cognitive Skills: Critically analyse data; Comprehensively assess errors in data; Test hypotheses using experimental data
- Subject-Specific/Professional Skills: Demonstrate sound laboratory and measurement skills; Follow good and safe practice in the laboratory.
- Demonstrate good team working
- Demonstrate financial budgeting
- Demonstrate timely planning of laboratory schedule
- Demonstrate ability to determine which experiments are necessary/unnecessary to provide desired outcome

AIM: To work in a team and experience a real-life research style analytical problem while carrying out appropriate analytical experiments determined by the team. You need to keep the costs of your research to a minimum, efficiently assign roles and tasks to team members and to write a report of your findings in a predetermined format. As this is a research project you will need to work independently and find solutions to questions yourselves within your team. This will be assessed by a joint team report (80%) plus an individual self-reflection document and a joint team self-reflection document and task log (20%). |
