  2. Atomic emission spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_emission_spectroscopy

    Atomic emission spectroscopy (AES) is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample.

  3. Emission spectrum - Wikipedia

    en.wikipedia.org/wiki/Emission_spectrum

    Emission spectroscopy is a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according to its electronic structure , and by observing these wavelengths the elemental ...

  4. Inductively coupled plasma atomic emission spectroscopy

    en.wikipedia.org/wiki/Inductively_coupled_plasma...

    It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. [1] The plasma is a high temperature source of ionised source gas (often argon).

  5. Elemental analysis - Wikipedia

    en.wikipedia.org/wiki/Elemental_analysis

    To qualitatively determine which elements exist in a sample, the methods are mass spectrometric atomic spectroscopy, such as inductively coupled plasma mass spectrometry, which probes the mass of atoms; other spectroscopy, which probes the inner electronic structure of atoms such as X-ray fluorescence, particle-induced X-ray emission, X-ray ...

  6. Photoelectric flame photometer - Wikipedia

    en.wikipedia.org/wiki/Photoelectric_flame_photometer

    Flame photometry is a type of atomic emission spectroscopy. It is also known as flame emission spectroscopy. [1] [2] A photoelectric flame photometer is an instrument used in inorganic chemical analysis to determine the concentration of certain metal ions, among them sodium, potassium, lithium, and calcium. [3]

  7. Atomic spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_spectroscopy

    In physics, atomic spectroscopy is the study of the electromagnetic radiation absorbed and emitted by atoms. Since unique elements have unique emission spectra, atomic spectroscopy is applied for determination of elemental compositions. It can be divided by atomization source or by the type of spectroscopy used.

  9. Hydrogen spectral series - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_spectral_series

    Spectral emission occurs when an electron transitions, or jumps, from a higher energy state to a lower energy state. To distinguish the two states, the lower energy state is commonly designated as n′, and the higher energy state is designated as n. The energy of an emitted photon corresponds to the energy difference between the two states ...
