*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 ...

Due to increasing environmental pollutants and global industrialization, food and water safety have become crucial concerns today. Ensuring that consumables are free from harmful contaminants is a ...

Atomic Absorption Spectroscopy (AAS) is a technique that deals with the absorption of electromagnetic radiation of free gaseous atoms at a specific wavelength. AAS allows the measurement of extremely ...

Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited ...

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 ...

Over the past few years, it has become possible to confine and guide light in micrometre-scale, hollow-core waveguides based on photonic-crystal structures, such as photonic-crystal fibre (HC-PCF) 6, ...

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 ...

Spectroscopy represents a scientific measurement technique for the studying of matter through its interaction with different components of the electromagnetic spectrum. It can measure light by ...

THE three Cantor lectures on the above subject, delivered by Prof. H. Dingle to the Royal Society of Arts in November and December 1934, have now been published (London: Royal Society of Arts, 1935.

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

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 ...
