Atomic absorption spectrometry is an analytical method to quanitify
target elemental concentrations in a sample by atomizing the sample at
high temperature, irradiating the sample with light of an element-specific
wavelength, and measuring its absorption.
It is called frame atomic absorption spectrometry when a sample is atomized in acetylene-air frames and such, and frameless atomic absorption spectrometry (or electrothermal atomic absorption spectrometry) when a sample is atomized in a graphite furnace.
