Why is the light "chopped" into pulses in AAS?
Hello,
I’m studying chemistry and I noticed that in a diagram of Atomic Absorption Spectrometer, it describes the light emitted by a hollow cathode lamp as being “pulsed”.
I was curious why it is pulsed. I cannot find a reason in the textbook or on the Internet, I was hoping someone could give me a clue.
Thanks!
