Prerequisites / Co-requisites
The module provides an introductory overview to the main techniques used in analytical chemistry providing understanding of the fundamental principles of the techniques as well as the mains aspect of their practical application. The combination of lectures an practicum allows the student to get familiarised with the common practises in an analytical chemistry laboratory (calibration of instrumentation, validation, analysis of quality control samples, etc.) as well to introduce them to health & safety regulations and risk assessment.
To describe and evaluate the fundamentals of analytical measurement of analyte concentrations, including safety procedures, calibration of equipment, data recording and the application of statistics in analytical chemistry
To improve the candidates awareness of health and safety issues, including in the practical laboratory
To describe and evaluate the principles, instrumentation, problem solving and practical aspects of atomic spectroscopy, chromatography and electrochemistry

Lectures 20-25: Introduction to separation science; basic chromatographic methods; classification; terminology; stationary and mobile phases; solute interaction; equations/calculations in chromatography; efficiency and resolution; Van Deemter equation; planar (TLC, paper) and column (LC and flash) chromatography.
38-hour practicum: Practical work on topics such as spectroscopy, basic laboratory good practice – titrations, electrochemistry, atomic emission spectroscopy and chromatography
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Introduce to the student to the fundamentals of the analytical techniques during the lectures. These would include the physical-chemical principles as well as design and operation of instrumental analytical techniques.
Discover hands-on the main aspects of the practical application of the techniques; which include sample preparation, operation and calibration of the instruments, validation by means of the quality controls and the analysis of unknown samples. The students have the opportunity to see and operate by themselves the equipment and methods described during the lectures.
Encourage the development of their critical assessment and self-evaluation skills by describing the main sources of error during the development of the practical experiments. They are encouraged to discover alternative techniques or methods that solve some of the problems encountered during the analyses. This will familiarise the students with the search of scientific literature and will promote the development of independent and critical thinking.
Understand and apply common calculations; at the end of the practical sessions the students should provide the results of their calibration, validation and analysis, which will allow the students to understand and apply common calculations and determination of analytical figures of merit. This is reinforced with the tutorial sessions during which the students have an opportunity to revise in small groups the calculations and discuss the application of the different approaches to the resolution of analytical problems.
The learning and teaching methods include:
Combination of lectures (25 hours), practical sessions (42 hours) and tutorials (4 hours)
The assessment strategy is designed to provide students with the opportunity to demonstrate:
Their understanding of fundamental principles of basic analytical techniques.
Their know-how of the chemical analysis practise.
Their competence to perform fundamental calculations.
Their capacity for independent/critical thinking by means of evaluation of their own results.
Thus, the summative assessment for this module consists of:
Evaluation of practical reports (40%)
Assessment of tutorial (10%)
Short Answer Test (exam) - 1.5 hours (50%)
The first practical reports and tutorial sessions are assesssed in order to provide feedback to the students, to help them understand the requirements for each piece of course-work and tackle any problems and the need of additional support/reinforcement to complete succesfully the module.
General feedback on the results and performance of the practical sessions is provided to all the students during the 50-min lectures prior the laboratory sessions; these pre-lab classes deal common mistakes (conceptual, practical or numerical), health & safety issues and reinforcing good practices.
All the students receive individual written feedback for their practical reports and tutorial and they have the chance to ask directly to the marker/facilitator. The assessment and feedback is carried out in a continuous way, therefore each of the students have feedback regarding their performance for the previous tutorial or practical session before they must submit the next piece of work. This allows the student to continuously improve, increasing their chances of success and building up their competence and confidence levels along the whole duration of the module.
