Atomic Absorption Spectroscopy is a quantitative analysis technique. By quantifying the absorption of radiation by gaseous atoms of a liquid or solid sample is used to determine the amount of elements present in the sample. Using this technique the elements present in bulk along with the trace elements present can also be quantified.

Following are the basic components of the AAS instrument:

• Light Source – There are various other lamps used as per the requirement but cathode lamp is widely used as a source.
• Sample Cell – Also known as atomizer which produce ground state atoms for atomic absorption
• Light measurement – Comprising of monochromator, detector & data system

The detection level of AAS is ppb i.e. parts per billion. AAS is highly useful in the pharmaceutical industry to detect the presence of toxic elements, it is also used in the food industry, petroleum, and also for biological system studies. There are several labs in India where you can get this analysis done. Visit lab atoz to get a list of material testing labs in India.
