And also, how does heating up gaseous metal bring metal atoms into ground state? By intuition, it should increase the energy level of the electron right?
Yes that's correct, however spectrometers will often take a "baseline" reading of any contaminant light and remove any of those matching wavelengths from the reading of the detector.

THANK YOU SO MUCH I COULDNT FIND ANYTHING ABOUT THE AAS PROCESS [also ik this is from the US but its helped an ATAR student from the land down under ]
Our videos are actually based on the NSW HSC syllabus 😊
ohh that makes more sense :D@@ScienceReady
that was a clearly detailed video ,i wish you could do one on ICP'S
Truly Exceptional
Excellent, well explained, short, clear, complete 👍👍👍👍
Very detailed information, thank you 😃
Thank you, I have an exam tomorrow and this saved me!
THANK YOU. IT WAS VERY HELPFUL.
Simply excellent. Thank you
Great video
well explained sir
Well-done
Very clear
Love this
u save me ✨👍
Question.. why you convert ppm tô mg/l? Ppm IS a partes It means volume and mg IS the Wright. Pb 1ppm of volume IS not 1mg pelo litet. Pls comment
Here's a thing I don't understand. Wouldn't the flame produce light and 'contaminate' the absorbance reading?

The electrons will relax and return to the ground state on their own after they have been excited by energy provided by the flame
@@OMNI-Infinity Usually they will simply take the reading for just the flame itself without the metal sample in it first.
Got chem exam in 2 days :)
Does AAS only analyse metal concentrations?
Good
👍👍👍👍👍
