Hello everyone,

I am a non chemistry guy, but I have stumbled upon a problem about spectrometry. What I want to understand is where does the equation

Intensity = concentration * factor

comes about. What is the intensity conc. and the factor in the above.

Also if there are other elements involved say if we looking at steel, and we are trying to determine the actual concentration of zn in the steel sample, and for arguments sake it contains traces of Ni and Cu along with Fe ofcourse. All these will show up in the spectrum and interfere in the equation. How do we set up the equation in this case, and I believe they have to be set up as matrices, Can anyone explain or make reference so that I can understand.

Many thanks,

P.S. I understand my question might not be as clear, I will try to clarify myself if you have difficulties.
