This module examines a range of modern analytical chromatographic and spectroscopic techniques. Discussion topics will include the quality control in analytical measurement; methods of analysis & validation,Two dimensional NMR Structure elucidation, Raman spectroscopy, Scanning and Transmission electron microscopy, AFM, chromatographic methods and strategy in analytical investigation.
Quality Control in Analytical Measurement
Laboratory design and method; reference methods; reference materials; traceability; accreditation schemes (NAMAS, VAM etc).
Atomic Spectroscopic Techniques
Review of atomic absorption spectrometry atomization processes in flame and electrothermal devices (ie the graphite furnace); interferences (chemical and spectral); control of chemical interferences by chemical modification and platform atomization; control of spectral interferences; application areas.
Atomic emission spectrometry - influence of temperature; excitation processes; local thermal equilibrium (LTE) conditions and non-LTE conditions, spectral interferences. Principles of inductively coupled plasma mass spectrometry: instrument design and components, sample introduction methods, ion transport and mass spectral interferences, use of alternative sampling techniques and reaction cell technologies. Examples of applications including process, environmental and forensic analysis.
Chromatographic Methods
Examples and applications of combined spectroscopy-chromatographic techniques – to include GC-MS, and LC-MS. Ionisation techniques. Also IRMS. Spectral manipulation and spectral libraries. Applications to structural elucidation and determination.
Strategy in Analytical Investigation
Problems of trace analysis. Sampling extraction techniques. A general review of the use and range of techniques for problem-solving in analytical chemistry. The use of a combination of techniques in analytical investigations including approach to chemical speciation of organics and inorganics
