Atomic absorption spectroscopy atomic emission spectroscopy lecture 18 detection limits â usually, atomic absorption based on electrothermal atomization has better sensitivities… atomic emission spectroscopy lecture 18. Sample solution vaporized and atomized in a flame. Atomic absorption spectroscopy (aas) aas was employed in the 1950's used for qualitative and quantitative detection. Radiation will absorb more at the center of the line. It's used for the determination of the presence and concentrations of metals in liquid samples. Atomic absorption methods measure the amount of energy (in the form of photons of light, and thus a change in the wavelength) absorbed by the any atom has its own distinct pattern of wavelengths at which it will absorb energy, due to the unique configuration of electrons in its outer shell.
The atoms of the same kind that are absorbing.
It is particularly useful for determining trace metals in liquids and is most independent of molecular form of the metal in sample. In atomic absorption spectroscopy (aas), the atomizer is only needed to atomize the sample, but electronic excitation is done by an external line light source in atomic emission spectroscopy (aes), the high temperature source is also responsible for the thermal (collisional) excitation of atoms.
