Thread: Atomic Absorption question

Does it matter if the target analyte atom is ionized in atomic absorption spectrometry? Explain.

Thank you!

Shure, it matters.

But I need a little more input from your side to be able to actually do your homework for you.

Well I initially thought no because not all of the analyte goes through the flame (some if it is disposed) and the atoms that do get ionized strike the cathode and sputter atoms from the cathode into the gas phase ... so if the target analyte atom isn't ionized, it wouldn't matter because there are still atoms being ionized. I also thought of ionization interference and how an increased amount of ions would decrease the absorption signal.
