Atomic Absorption Spectroscopy

Atomic Absorption (AA) occurs when a ground state atom absorbs energy in the form of light of a specific wavelength and is elevated to an excited state. The amount of light energy absorbed at this wavelength will increase as the number of atoms of the selected element in the light path increases.

The relationship between the amount of light absorbed by analytes exist in known standards with a specified concentration and amount of light absorbed by unknown sample can determine the sample concentrations.

Performing atomic absorption spectroscopy requires a primary light source, an atom source, a monochromator to isolate a specific wavelength of light to be measured, a detector to measure the light accurately, the electronics to process the data signal and a data display or reporting system to show the data.

Atomic absorption spectroscopy is an incredible method with multi-purpose applications which has the ability to analyze 75 metal and metalloid elements.

Atomic Absorption Spectrometer used in the specialized laboratory of Sepahan Daneh is capable of measuring concentrations of toxic trace elements of different samples such as arsenic, mercury, lead and cadmium, and also other common elements such as calcium, sodium, magnesium, copper, iron, zinc, chromium, cobalt, sodium and manganese.
