Atomic absorption spectroscopy
Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.
In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine over 70 different elements in solution or directly in solid samples used in pharmacology, biophysics and toxicology research.
Atomic absorption spectroscopy was first used as an analytical technique, and the underlying principles were established in the second half of the 19th century by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff, both professors at the University of Heidelberg, Germany.
The modern form of AAS was largely developed during the 1950s by a team of Australian chemists. They were led by Sir Alan Walsh at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Division of Chemical Physics, in Melbourne, Australia.

Stupify
by: DisturbedYeah, bringing you another disturbing creation
From the mind of one sick animal who can't tell the difference
And gets stupefied
I've been waiting my whole life for just one fuck
And all I needed was just one fuck
How can you say that you don't give a fuck
I find myself stupefied, coming back again
All I wanted was just one fuck
One tiny little innocent fuck
And when I feel like I strayed out of luck
I find myself stupefied, coming back again
Why do you like playing around with my narrow scope of reality?
I can feel it all start slipping, I think I'm breaking down
Why do you like playing around with my narrow scope of reality?
I can feel it all start slipping away
See but I don't get it
Don't you think maybe we could put it on credit?
Don't you think it can take control when I don't let it?
I get stupefied, it's all the same you say, live with it
But I don't get it
Don't you think maybe we could put it on credit?
Don't you think it can take control when I don't let it
I get stupefied, I get stupefied
All the people in the left wing rock
And all the people in the right wing rock
And all the people in the underground rock
I find myself stupefied, coming back again
All the people in the high rise rock
And all the people in the projects rock
And all la hente in the bario rock
I find myself stupefied, coming back again
Why do you like playing around with my narrow scope of reality?
I can feel it all start slipping, I think I'm breaking down

Don't you think it can take control when I don't let it?
I get stupefied, I get stupefied
[Incomprehensible]
And don't deny me
No baby now, don't deny me
And darlin', don't be afraid
But I don't get it
Don't you think maybe we could put it on credit?
Don't you think it can take control when I don't let it?
I get stupefied
Look in my face, stare in my soul
I begin to stupify
Look in my face, stare in my soul
I begin to stupify
Look in my face, stare in my soul
I begin to stupify
Look in my face, stare in my soul
I begin to stupify
Look in my face, stare in my soul
Look in my face, stare in my soul
Look in my face, stare in my soul
Look in my face, stare in my soul
Look in my face, stare in my soul
Look in my face, stare in my soul
Look in my face, stare in my soul
