On completion of this subject the student should be able to:
1. Gain basic experiences on the theory and operational aspects of instrumentation used for analysis of a variety of samples;
2. Comprehend the principles of flame atomic absorption spectroscopy (FAAS) and flame emission spectroscopy (FES);
3. Comprehend the instrumentation used for FAAS and FES, and to account for interferences in FAAS and FES;
4. Describe the glass (pH) electrode and ion selective electrodes, and to describe the application of the Nernst equation;
5. Comprehensively discuss the use of ion selective electrodes in analysis.
Atomic absorption spectrometers: Hollow cathode lamps, atomisers, monochromators, single and double beam instruments, background correction, flame chemistry and interferences, releasing agents, survey of metals amenable to FAAS; The glass electrode: response to H+ and to Na+, solid state, membrane and ion exchange ion selective electrodes, gas sensing electrodes, fluoride, sulphide, cyanide and halide electrodes, metal sensing electrodes.
