Atomic Absorption Spectrometer Price Simulately Soil Elements Analyzer Aas
* Atomic absorption spectroscopy is a measurement method based on the absorption by ground-state atoms of characteristic wavelengths.
* Normally, atoms are in the ground state. For each element, the energy for their atoms to transit from the ground state to the exited state is known and called characteristic spectral lines. For atomic absorption spectroscopy, a hollow cathode lamp (HCL) is used as the light source to emit the light of the wavelength characteristic of an element. Then the light passes through the atom vapor which absorbs the light of the characteristic wavelength. The concentration of atom concentration of the element is calculated based on the absorption of the light.
After a beam with intensity of I0 passes through the media with atomic concentration of C, the intensity is decreased to I, by following the Lambert-Beer law.
A = lg(I0 /I) = KCL
A: Absorbance
I0: Incident ray intensity of characteristic spectral lines
I: Emergent ray intensity of characteristic spectral lines
k: Absorbance factor
L: Flame distance passed by ray of characteristic spectral lines
C: Atomic concentration
The equation indicates that the absorbance and atomic concentration is in a linear relationship in certain circumstances.
