Applications of Atomic Absorption Spectroscopy AAS

The atomic absorption spectroscopy technique is widely used for quantitative analysis. Applications of atomic absorption spectroscopy are given below:

Clinical Analysis

This technique is widely used in the clinical analysis of various metals, although this technique is capable of analyzing many elements (both metals and non-metals), including trace elements that can be transformed into atomic form after vaporization. E.g. analysis of toxic material and metal in blood.

Environmental Analysis

Analysis of heavy metal and toxic material such as Lead, arsenic, cadmium, and mercury in abiotic components (air, water).

Pharmaceutical analysis

In pharmaceutical industries, cadmium is used as a catalyst. By atomic absorption spectroscopy we can easily attain its spectra. IV solutions are also analyzed by this technique.

Industrial Analysis

In industry, elemental analysis is used to measure the number of metals (lead, calcium, cadmium, etc.) in mining.

Herbal drug formation

This technique is used to check the metallic component in the drug.

Petroleum Analysis

The number of impure substances and metals (sodium, magnesium, zinc) can be measured by atomic absorption spectroscopy.

Agriculture

In agriculture, soil and plant analysis for the detection of heavy metals. It helps to investigate chemicals in the soil. To analyze the use of fertilizer this technique is helpful.

Food Analysis

In the food industry, metals and impure substances are detected by this technique such as the purity of milk.

Textile Analysis

In the textile industry, Elemental analysis of fiber is done by atomic absorption spectroscopy.
