atomic emission spectroscopy

[ə¦täm·ik ə¦mish·ən spek′träs·kə·pē]
(spectroscopy)
A form of atomic spectroscopy in which one observes the emission of light at discrete wavelengths by atoms which have been electronically excited by collisions with other atoms and molecules in a hot gas.

The concentration of Cu and Ni in the electrolytes, after the polarisation experiments in the presence and absence of different concentrations of studied inhibitors, is determined by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICPAES).
The metal substrate used was aluminum alloy 2024-T3, containing 4.31 wt% Cu, 1.5 wt% Mg, 0.6 wt% Mn, 0.08 wt% Si, and 0.17 wt% Fe, as determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES).
The volume begins with papers on atomic emission spectroscopy, including discussions of the use of microwave digestion and inductively coupled plasma to determine elements in petroleum samples, fuel analysis by filter furnace electrothermal atomic absorption spectrometry, and rotrode filter spectroscopy.
Sometimes referred to as ICPAES (atomic emission spectroscopy) or ICP-OES (optical emission spectroscopy), ICP spectroscopy works by measuring the photon wavelengths produced by excited electrons to identify the signatures of specific elements.
Rock samples on the project are assayed for gold by standard 30-gram fire-assaying with inductively coupled plasma atomic emission spectroscopy (ICP-AES; Au-ICP21) or gravimetric finish (Au-GRA21) at ALS Minerals laboratories in Vancouver, British Columbia.
