principle of spectrophotometer

...Spectrophotometer Introduction of Atomic Absorption Spectrophotometer Atomic absorption spectroscopy (AAS) is based upon the principle that free atoms in the ground state can absorb light of a certain wavelength. These very specific wavelengths give the technique excellent specificity and detection limits in the AAS analysis. Parameters of Atomic Absorption Spectrophotometer
