Atomic absorption spectroscopy - Wikipedia
Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative measurement of chemical elements. AAS is based on the absorption of light by free metallic ions that have been atomized from a sample.

10.4: Atomic Absorption Spectroscopy - Chemistry LibreTexts
Atomic absorption spectroscopy is ideally suited for the analysis of trace and ultratrace analytes, particularly when using electrothermal atomization. For minor and major analytes, sample are diluted before the analysis. Most analyses use a macro or a meso sample.

Atomic Absorption Spectrophotometry: Principle, Parts, Uses - Science Info
Atomic absorption spectrophotometry is a widely used analytical technique that involves the measurement of the absorption of electromagnetic radiation by atoms in the gas phase.

1.4: Introduction to Atomic Absorption Spectroscopy
Atomic emission spectroscopy measures the intensity of light emitted by the excited atoms, while atomic absorption spectroscopy measures the light absorbed by atomic absorption. This light is typically in the visible or ultraviolet region of the electromagnetic spectrum.

Atomic Absorption Spectroscopy - an overview - ScienceDirect
Atomic absorption spectrometry (AAS) is a technique in which free gaseous atoms absorb electromagnetic radiation at a specific wavelength to produce a measurable signal. The absorption signal is proportional to the concentration of those free absorbing atoms in the optical path.

Atomic Absorption Spectroscopy, How Does AAS Work, AAS FAQs - Agilent
Learn about the basics of atomic absorption analysis and design. The FAQ addresses such questions as what is atomic absorption spectroscopy, how does it work and why use it. It also describes the key features of the instruments, and other important factors that can impact successful elemental analysis by AAS.

Atomic Absorption Spectroscopy: Instrumentation - Science Info
Atomic absorption spectroscopy determines the concentration of elements in a liquid sample by absorbing energy from specific wavelengths of light (often 190 to 900 nm). It is a technique for determining the concentration of metal atoms/ions in a material.

Atomic Absorption Spectroscopy - an overview - ScienceDirect
Atomic absorption spectroscopy is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.

Atomic Absorption Spectrometry (AAS) Information | Thermo Fisher ...
What is atomic absorption spectrometry? Atomic absorption spectrometry (AAS) detects elements in either liquid or solid samples through the application of characteristic wavelengths of electromagnetic radiation from a light source.

Atomic Emission and Absorption Spectra: Definition and Formula
Atomic absorption spectroscopy (AAS) is a widely used analytical technique for quantifying trace elements in various samples. It relies on the principle of light absorption by free atoms in the gaseous state.
