The following topic materials will be presented:
Chromatography: A more extended treatment of sorption mechanisms and fundamental concepts in chromatography - plate theory, Van Deemter treatment and capacity factor as applicable to Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC) will be presented together with coverage of the principles of operation of detectors, types and selection of stationary phase; capillary columns and instrumental requirements. Quantitative procedures as applicable to chromatographic methods in general will be detailed.
Atomic Spectroscopy: instrumentation, sample vaporisation, quantitative measurements and interferences. Molecular absorption spectrometry; uv/visible and infrared. Quantitative methods, internal standards. Fluorescence analysis; principles and applications.
Voltammetry: electrode systems; DC polarography, characteristics, ; pulse polarography normal and differential, detection limits and resolution. Stripping voltammetry, cathodic and anodic, linear sweep and differential pulse; applications, limitations and interferences. Potentiometry; ion-selective electrodes, calibration and selectivity, detection limits and response times; theory and construction of electrodes, glass, liquid ion-exchange, neutral carrier and insoluble salt types; applications and limitations of ion-selective electrodes. Introduction to electrochemical sensors. Gas sensors e.g. Clark cell (oxygen sensor), CO2, NH3.
The use of carbon and proton NMR spectroscopy for structure identification.
A series of laboratory exercises designed to reinforce and complement the lecture material.
The Graduate Attributes relevant to this module are:
- Academic: critical thinker, analytical problem solving, autonomy, group work
- Personal: motivation, time keeping
- Vocational: collaboration, research, analytical techniques
- This module will be prefaced with a review of the scope and philosophy of analytical chemistry. Choice of method, sampling collection and preparation.
A series of laboratory exercises designed to reinforce and complement the lecture material by application of instrumental techniques to “real” samples as far as practicable will be completed.
