Exercises

Atomic spectroscopy Part 2

1) What are some of the interference types that can be encountered in atomic absorption spectroscopy? What about in atomic emission spectroscopy? How can these interferences be overcome?

2) How does a sequential atomic emission spectroscopy instrument work? What about a simultaneous instrument?

3) Compare and contrast flame atomic absorption spectroscopy, inductively coupled plasma emission spectroscopy, and inductively coupled plasma mass spectrometry with regard to instrument design and performance.

4) What is the chemical basis behind the operation of an energy dispersive x-ray fluorescence spectrometer? What are some of the advantages of this instrument over ICP-AES/FAAS/ICP-MS?
