ETAAAS stands for Electrothermal Atomic Absorption Spectroscopy. It is an analytical technique used in chemistry to determine the concentration of different elements in a sample with high accuracy and precision. ETAAAS is based on the principle of atomic absorption spectroscopy, which measures the absorption of light by atoms in the sample.
In ETAAAS, a sample is first heated to a high temperature, typically by using a graphite furnace. This causes the atoms in the sample to vaporize and form a cloud of vapor. The vaporized atoms are then exposed to a beam of light with a specific wavelength that is characteristic to the element being measured. The atoms absorb the specific wavelength of light proportional to their concentration in the sample, and this absorption is detected by a detector.
By measuring the absorption of light at the specific wavelength for a particular element, the concentration of that element in the sample can be determined. ETAAAS is highly sensitive and can detect trace amounts of elements in samples, making it a valuable technique in various fields such as environmental analysis, pharmaceuticals, and industrial quality control.
Overall, ETAAAS is a sophisticated analytical technique that allows precise and accurate determination of element concentrations in samples using the principles of atomic absorption spectroscopy, which involves the vaporization of atoms and their subsequent absorption of light at specific wavelengths.
