  1. Tutorial CM 4004 All material required to answer the following questions are contained in the lecture notes.

  2. Questions 1/ Give 3 examples of both fuel and oxidants used in AAS.Which combination of fuel/oxidant can achieve the highest temp in AAS? 2/ List three zones of an AAS Flame? 3/ Name three different types of interference in flame AAS and describe ways in which they can be overcome 4/ Explain how the Doppler Effect accounts for the symmetric distribution of wavelengths absorbed by an atom. 5/ List the steps in electrothermal atomization in graphite furnace AAS

  3. Questions 6/ Explain how the L’vov platform performs compared to wall atomization in graphite furnace 7/ Why is peak area measurement preferable to peak height measurement? 8/ What are the component parts of a hydride generation apparatus? 9/ Describe the series of events required to form a plasma in ICP spec. 10/ Distinguish between AAS and AES giving reasons why AES spec are more complex 11/ What is the typical temp range of an ICP?

  4. Questions 12/ List the characteristics of ICP 13/ Draw a diagram to illustrate the optical layout of an ICP detector 14/ Draw a diagram to show how and interface couples the atm. pressure of an ICP to a high vacuum MS 15/ State the processes which a sample must undergo as it travels through the plasma before proceeding to a mass spectrometer in ICP-MS. Use a diagram to illustrate these processes. State the main factors which affect these processes. 16/ What are four main design considerations of spectrometer components which influence performance? Explain how two of these factors influence ICP performance.
