Atomic Absorption Spectrometry and its Applications

Atomic Absorption Spectrometry and its Applications

The module covers the basic principles of atomic absorption spectroscopy and provides an overview of the components and operation of the spectrometer .​


  • Principle of atomic absorption spectroscopy and the detectable elements using AAS.​

  • Usage of AAS in identification and quantification of different elements with an example​

  • Components of a typical atomic absorption spectrometer​

  • Introduction to atomizers and atomization process​

  • Types of interference and its impact​

  • Calibration curve and its use in determining the final concentration of the elements​

  • Precautions while handling an AAS instrument​

  • Why it matters

    AAS is a highly sensitive technique that can measure element concentration in the order of parts per billion. It can be used to detect the presence of metallic impurities and determine quantity of elements in agricultural and food products (for example, quantify copper in brain tissue), water bodies, wastewater, sludge and suspensions. Understanding the science behind AAS and operating a spectrometer is crucial  for analysts.​

  • Who is it for​ ​

    This module is relevant to all employees in analytical quality teams including quality control and quality assurance, who are involved in performing and reviewing results from AAS.​
