Summary module description:
The aim of this module is to introduce students to a wide range of analytical techniques.

The aim of this module is to introduce students to a wide range of analytical techniques.

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 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 and thermal 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. W C Hayes (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 (5 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.

Other information on summative assessment:

Beginning of Term Test (Spring Term) - 20%. Examination - 80%. Students attend workshops on the material covered in this module. Attendance is compulsory.

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

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at:
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

    Length of examination:
    1.5 hours

    Requirements for a pass:
    A mark of 40% overall

    Reassessment arrangements:
    Reassessment will be held in August 2016 and will be by examination only worth 100%.
