The module is designed to give students experience of a range of advanced laboratory methods with wide application in the Chemical Industry and modern Forensic Science. These methods will underpin Stage 4 research projects (PS740 and CH740) as well as advanced concepts in the Stage 4 program.Gas chromatography – mass spectrometry
The module will be in two sections. In the first section, taught in the Autumn Term, students will receive training in a range of advanced chemical and physical laboratory methods. This section of the module will be assessed by a report written on each experiment. In the second section, beginning towards the end of the Autumn term and continuing throughout the Spring Term, students will select a topic for an extended self-directed literature review. This will evaluate the available literature on a subject and allow the student to develop critical thinking. This section of the module will be assessed by oral presentation and a written dissertation.
Experiments will include such as (NB this is an illustrative list):
Important example of modern hyphenated analysis techniques. Used in analysis of accelerant and explosive traces at scenes of fires and explosions, also in analysis of drugs of abuse.
Atomic absorption spectroscopy
Used in the analysis of trace metal content. Experiment to compare flame and graphite furnace methods.
Universally used in analysis of organic substances. Experiment to manipulate FID curves, to explore peak resolution and detect contaminants in samples such as counterfeit medicines.
Used in analysis of metal artefacts, including bullet casings and forged coins.
Used in analysis of materials with crystalline lattices, including metals and inorganic explosives residues.
SEM, TEM and Electron Probe Microanalysis (EPMA) in the analysis of gunshot and explosives residues.
Used in forensic analysis of ink pigments, street drugs and counterfeit pharmaceuticals.
Widely used method of separating and identifying substances in forensic science.
Used in comparison of pigments and paper in questioned documents; also chemical tests for explosives and drugs of abuse.
Facial recognition software, signature comparison, and the reconstruction of CCTV images.
This module appears in the following module collections.
8 x 2 hour lectures, Training session 1 x 4 hr
Workshops 4 x 2 hr, 6 (6 hour) laboratory days.
This module is expected to occupy 300 total study hours including the contact hours above.
This is not available as a wild module.
Method of assessment
100 % Coursework: The first section of the module will be assessed by a report (1,000 word equivalent) written on each experiment, with detailed analysis of the results obtained in the laboratory. 45% of the marks.
The project component of the module (55% of marks) will include presentation and dissertation (5,000 words). The presentation will give an oral overview of the planning, experimental work and conclusions in the project. The dissertation will include a detailed account of the measurements made in the laboratory to establish the detection limit of the chosen experimental method, together with a critical literature survey of the application of the method in Forensic Science, including recent casework.
Literature as indicated by the project supervisor.
