Objectives On completion of this subject, students will be able to describe the appropriate sample preparation techniques required of solid, and liquid samples; describe the appropriate technique to apply for the quantitative multi-elemental analysis of a sample; discuss and describe the principles underlying a range of analytical methods for quantitative analysis including XRF, OES (ICP and arc/spark), AAS, IC and polarography; understand the nature of several important multi-element analytical methods required for quantitative trace analysis, including ICP-MS, AAS (Graphite furnace) and anodic stripping polarography; demonstrate the basic practical skills and knowledge required to apply a broad selection of the analytical techniques covered in this course; understand the principles which underlie the reliability and accuracy of analytical methods for elemental analysis including statistical considerations, errors and standardisation, special needs for trace analysis, interferences, procedural limitations and detection limits and demonstrate a basic knowledge of modern automated techniques for elemental analysis.

Synopsis This subject is designed to provide students with a knowledge and understanding of the chemical principles underlying simultaneous/sequential multi-element analysis. The subject matter covered includes sample preparation techniques, qualitative characterisation and quantitative analysis using a range of methods and instrumentation including XRF, OES (ICP and arc/spark), AAS, ion-chromatography, polarography, automated analysis including autoanalysers, flow injection methods and autosampling. In addition, students will gain an understanding of certification requirements, statistical considerations, errors and standardisation, interferences, limitations and meaning of a result in relation to the methods studied. The practical work and demonstrations constitute an integral part of the subject and will expose students to the techniques listed.

Assessment Written examination on theoretical material: 60% - Assignment work: 15% - Laboratory work: 25% - A pass in both the theory and practical components of the course is mandatory.
