The aim of this module is to introduce students to a wide range of analytical techniques and provide training in career management skills.

Assessable learning outcomes:
Students should be able to:
• Describe and discuss the subject matter of the module, and explain the concepts raised within it.
• Critically examine questions raised in tutorials and workshops, and analyse numerical and other problems.

Additional outcomes:
The students should improve their team-working skills through workshops, numeracy through problem solving, and oral and presentation skills through tutorials. In addition students should begin to develop the skills necessary for future employment.

Outline content:
M J Almond (2 lectures) Introduction to Analytical Methods
Choice of analytical methods, methods of sampling; qualitative and quantitative analysis; precision and accuracy, standard deviation.

M J Almond (8 lectures + -2 x 2 hr workshops) UV, AA and IR Spectroscopy, Thermal Methods
Introduction to spectroscopic methods. Design of the UV-visible spectrometer; quantitative analysis using UV-visible spectroscopy - the Beer-Lambert law. Atomic absorption spectroscopy for the determination of elemental composition. Fourier transform and dispersive infrared spectrometers. Use of infrared spectroscopy for functional group analysis in organic and inorganic chemistry. Introduction to concepts of symmetry using CO2 and SO2 as examples. Introduction to use of isotopic substitution in infrared spectroscopy. Thermogravimetric analysis (TGA) and differential thermogravimetry (DTG) and differential thermal analysis (DTA) and applications of the methods.

R K Cramer (7 lectures + 1 x 1 hr workshop) Mass Spectrometry and Chromatographic Techniques
Introduction to mass spectrometry. EI techniques, precise molecular weights, metastable peaks, fragmentation and rearrangements. Principles and applications of gas-liquid chromatography and high performance liquid chromatography.

G Brown (6 lectures + 1 x 1 hr workshop) Nuclear Magnetic Resonance Spectroscopy
Theory and practice of NMR. Spectrometer design for a CW-NMR instrument. Origins and interpretation of chemical shift and peak splitting in 1H NMR spectra (including second order effects and the magnitude of coupling constants). Chemical shift in 13C NMR. Interpretation of 1H NMR spectra from molecules of known and unknown structure. Introduction to 2-dimensional methods.

Brief description of teaching and learning methods:
Approximately two one-hour lectures per week with roughly one workshop on related material every two weeks. This module closely relates to practical analytical chemistry in module CH2PRAC and students are expected to utilise private study time in module CH2AN3 to support their work in module CH2PRAC.

Summative Assessment Methods:

Method Percentage
Written exam 80
Set exercise 20

Other information on summative assessment:
Coursework 20%
Assessed Workshop 20%
Students attend workshops on the material covered in this module. Attendance is compulsory at both. Lectures and workshop problems form the basis of assessed problem solving workshop (1.5 hours) held at the end of the autumn term.

Examination 80%

Formative assessment methods:
Workshops on problems of the type encountered in tutorials and examinations.

Penalties for late submission:
For students on chemistry-based degree courses any unexplained absence from more than two workshops will automatically incur a formal warning from the Department Director of Teaching and Learning.

Length of examination:
2 hours

Requirements for a pass:
A mark of 40% overall

Reassessment arrangements:
Reassessment by examination in August or September.
