Atomic Absorption Spectroscopy: Sample Atomization

Atomic absorption spectroscopy uses sample atomization to turn a liquid specimen into free atoms for analysis. The two main approaches are flame atomization and electrothermal atomization. Both methods prepare the sample so its atoms can be measured by the instrument.

Flame atomization uses a neb...

AAS usually atomizes samples through flame or electrothermal atomization.

Flame atomization typically uses a nebulizer to continuously aerosolize the sample and a spray chamber assembly to mix it with fuel and oxidant.

Only about five percent of the aerosol droplets are fine enough to reach the flame, where they desolvate in the pr...
