The SavantAA Zeeman combines the longitudinal Zeeman-effect with programmable magnetic field strength, transverse heating of the graphite tube and the latest in surface-mount technology to give a ...
Atomic Spectroscopy is the technique used to determine the electrical components of the analyte through its mass spectrum. Nowadays, several techniques are available, and choosing the right one ...
For more than thirty years, heavy metals have been considered potential toxic environmental contaminants. It is a fact that most of today’s environmental challenges revolve around the determination of ...
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 ...
In X-ray crystallography, X-rays of sufficient energy are used to excite the inner shell electrons in the atoms of a sample. The electrons move first to the outer orbitals and then down into the ...
*If you learn how to use atomic absorption spectroscopy (AAS), you can do accurate and reliable chemical research. But it takes practice and concentration to fully grasp its basic ideas. Understanding ...
