Atomic absorption spectroscopy. (AAS)?

1.Briefly describe the principles of operation and the major components of the spectrometer.

2. Is there anything else in the instrument (aside of the sample) that could absorb light from the light source? Will this affect the results obtained? Why/why not?

3. Is the this analytical procedure qualitative or quantitative, or both? Explain fully.

Update:

Thanks in advance :)

    This is a pretty good article about AAS:

    You have probably seen the Wikipedia section:

    2. If you are worried about light absorption from your solvent, just run a solvent blank to see if there are any absorption lines where your sample lines are found.

    3. The spectral lines give you a qualitative analysis. If you run standard solutions of different concentrations around the sample concentration, you should be able to get quantitative data, too.

    the two could be utilized, atomic absorption is greater precise because of the fact greater of the atoms are excited, so which you get a greater effective/greater solid interpreting indra, you in simple terms contradicted your self! Na is a metallic and can be analysed by utilizing flame emission spectroscopy
