The basic principles of AAS can be expressed as follows. Firstly, all atoms or ions can absorb light at specific, unique wavelengths. When a sample containing copper (Cu) and nickel (Ni), for example, ...

Flame Atomic Absorption Spectroscopy (FAAS) is a very popular analytical technique that has been employed by researchers for the elemental analysis of trace metals in a variety of samples. How does it ...

What is Atomic Absorption Spectrometry? AAS is a technique for determining how much of a specific element is present in the specimen under study. The uptake of optical radiation by neutral atoms in ...

This live online, instructor-led course looks at the technique of Atomic Absorption Spectroscopy (AAS) from the initial choice of analytical set-up through to method development; including sample ...

Researchers led by Prof. ZHOU Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom ...
