Atomic Absorption


This method is used for the determination of metals content of samples using flame atomic absorption. A sample is initially ashed and digested in a strong acid. The solution is filtered and sprayed into a flame where a beam of light of a given frequency passes through to a detector. Some of the light is absorbed by the ions in the flame giving an indication of the concentration of metal in the sample relative to a calibration curve. This method is currently used for: sodium, potassium, vanadium, iron, aluminum, copper, nickel, manganese, and silicon.
