Atomic Absorption Spectrometers

An atomic absorption spectrometer is an analytical instrument used to determine the concentration of specific chemical elements in a sample by measuring the absorption of light at characteristic wavelengths. It is commonly used in analytical chemistry for quantitative analysis of metals and metalloids in various samples, including environmental, biological, pharmaceutical, and industrial samples.

Glossary

spectrometer A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
