High-resolution atomic absorption spectrometry (HR AAS) has emerged as a powerful tool for the determination of trace and ultratrace elements across a wide range of disciplines. By employing a ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

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 ...
