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, ...

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 ...

Atomic Absorption Spectrscopy (AA) is an important spectrophotometric technique for analyzing samples for a particular element. The spectrophotometer uses an acetylene flame as the sample cell and ...

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 ...

Milk is one of the fundamental food groups in the human diet, both as various dairy products and in its original state. The 2008 Chinese contaminated baby formula scandal increased awareness amongst ...

Fossil fuels are widely used in automobiles, industry, and power plants, but due to excessive use they are depleting at a rapid rate. This has prompted a search for renewable, sustainable, and ...

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 ...

Analytical spectrometry encompasses a diverse range of techniques that measure the interaction of electromagnetic radiation with matter, providing both qualitative “fingerprints” and quantitative ...

From a eureka moment in the garden to an Australian innovation that launched a multi-million dollar industry IN 1952, AN UNASSUMING Australian scientist was working in his garden when an idea came to ...

*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 ...
