    After completing this unit the student will be able to:

    • Compare and contrast the advantages of flame, furnace and inductively coupled plasma atomization sources.
    • Justify why continuum radiation sources are usually not practical to use for atomic absorption spectroscopy.
    • Describe the design of a hollow cathode lamp and justify the reasons for a hollow cathode configuration and low pressure of argon filler gas.
    • Devise an instrumental procedure to account for flame noise in atomic absorption spectroscopy.
    • Devise an instrumental procedure to account for molecular absorption and scatter from particulate matter in atomic absorption spectroscopy.
    • Describe three possible strategies that can be used to overcome the problem of nonvolatile metal complexes.
    • Devise a procedure to overcome excessive ionization of an analyte.
