PRINCIPLES OF ANALYTICAL CHEMISTRY - 2021/2
Module code: CHE1044
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
The module gives an introductory overview of the main techniques used in analytical chemistry. It provides understanding of the fundamental principles of chemical analysis as well as the main aspects of their application. The combination of lectures and practical sessions allows the students 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.

|Assessment type||Unit of assessment||Weighting|
|Examination||Examination: 1.5 hours||70|
Failure in the laboratory may require re-assessment through a defined practical examination
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 practice.
- their competence to perform fundamental calculations.
- their capacity for independent/critical thinking and problem solving.
Thus, the summative assessment for this module consists of:
• Examination 1.5 hours (70%) – Learning outcomes 1, 2 & 3.
• Evaluation of laboratory portfolio (30%) - Learning outcomes 2, 3 & 4.
The first 2 practical sessions are assessed in order to provide feedback to the students, to help them understand the requirements for the coursework, and to provide additional support/reinforcement to complete successfully the module.
General feedback is provided to all the students during the pre-laboratory sessions and tutorials; these classes deal with common mistakes (conceptual, practical or numerical), health & safety issues and reinforcing good practice.
All the students receive individual written feedback for their practical reports.
- provide understanding of the theoretical principles, instrumentation, calculations and problem solving aspects of atomic & molecular spectroscopy, chromatography and electrochemistry.
- describe the fundamentals of the analytical sequence including sample preparation, operation & calibration of equipment, data recording and quality assessment of chemical data.
- develop the students’ practical skills on the use of basic spectroscopy, chromatography and electrochemical instrumentation in a laboratory environment.
- improve the students’ awareness of health and safety issues.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
• introduce the students 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.
• have hands-on experience in an analytical laboratory; including practice in sample preparation, operation and calibration of the instruments, validation and analysis of unknown samples.
• encourage the development of their self-evaluation skills by describing the main sources of error during the practical experiments, nurturing problem solving skills and critical thinking.
• understand and apply calculations in analytical chemistry during the practical sessions. 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)
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
