difference between AAS & flame photo meter ?..

Answer / kashif

Flame photometry is a kind of atomic emission spectroscopy.
The sample is excited,causing the ejection of light. the
wavelength of the emitted light is a function of the energy
of the excited electrons, so every element has a
characteristic set of wavelengths. usually a single
wavelength is detected & the intensity of the emission is
used to determine strength.

In AAS A light of a standard wavelength is passed through a
flame consist of unknown substance, & the concentration of
the required element is determined by the reduction in the
energy of this light as it passes through the flame. the
light is adsorbed by the electrons in the required element,
kicking them into a higher orbit or completely out of the
atom, depending on the energy involved.
