Do Ions in a Plasma Affect Atomic Absorption Spectroscopy Results?

Click For Summary
SUMMARY

The discussion confirms that Atomic Absorption Spectroscopy (AAS) requires the entire sample to be in solution, as solids cannot be aspirated into the flame. When measuring zinc, both dissolved ions and solid zinc must be converted to a liquid form for accurate absorption readings. The plasma generated in the AAS flame contains various elements, including zinc ions, which contribute to the absorption spectrum. Therefore, the presence of ions in a plasma does affect the results of AAS, as only the ionic form can be accurately measured.

Are the results of Atomic Absorption Spectroscopy affected if the metal were ions? For example, if you were trying to measure the amount of zinc in a sample but part of it was dissolved as ions and other parts were simply solid, would they measure the same absorption or would the ions not be counted?

What wavelength is used in AAS?
 
In AAS the entire sample must be in solution since it is aspirated into the flame (solids are a no-show). The flame is a plasma of several things including zinc, if that's what is being analyzed. What role do ions play in a plasma?
