Balance of independent study and scheduled teaching activity
Teaching and learning sessions include lectures/workshops (36 h), tutorials (16 h), practical (8 h) with feedback where appropriate. Tutorials have an emphasis on problem solving based on pre-set work with student participation. Students will be expected to prepare in advance for tutorials to develop problem-solving skills using worksheets provided. Feedback from these sessions facilitates the learning process. Self-managed time and private study (222 hours) should be spread out over the semester and not left until the final weeks. Lectures are used to set context and to deliver subject material, and are linked to tutorials, practicals and problem sessions. Students will be expected to reflect on the learning experience and develop their own understanding of the material.
On successful completion of this module the student will be able to:
1. Describe the steps involved in a chemical analysis;
2. Outline the theoretical basis for selected analytical techniques and describe the instrumentation required
3. Use instrumental data to calculate the concentration of analyte in a specified sample
4. Evaluate any errors arising from a determination and assess the reliability of the results obtained;
5. Understand the basic principles and theory behind NMR spectroscopy, mass spectrometry, IR spectroscopy and Raman spectroscopy;
6. Interpret simple spectra;
7. Analyse spectroscopic data to predict the chemical structure of a compound;
8. Use the preparation of a portfolio
The module will be assessed by a mix of time-constrained assessments of varying length, and a practical report.
There will be two short-answer progress tests one of 30 min duration (10%) - this will assess the ability of students to perform appropriate calculations and to describe accurately the principles of the analytical methods and to assess understanding of the principles of chromatography. This element will provide both summative and formative assessment. The second of 1 h duration (25%) will examine the students’ understanding of UV/Visible spectrometry and electrochemistry as well as their grasp of the principles of analysis and ability to use results to calculate levels of the analyte in samples appropriately. This element will provide both summative and formative assessment.
The coursework component will require completing the practical session and reporting the results in the style of a Journal article, which will also develop communication skills and engaging with the literature (15%).
The qualitative spectroscopy will be assessed by a series of interpretation exercises involving the use of IR, MS and NMR spectra to predict the chemical structure of unknown compounds (15%). This will provide both formative and summative feedback.
The principal summative component will be the end-of-module exam (1 1/2 h, 25%) which will provide assessment of the ability to describe relevant analytical methods accurately, perform appropriate calculations, draw appropriate conclusions from data and communicate this clearly. This assessment will focus on material presented from week 15 onwards.
To pass the module, students need to achieve a minimum aggregate mark of 40%. There will be an attendance requirement for the practical sessions. If the module is passed on reassessment, then the maximum mark awarded will be 40%.
