The reason for atomic emission to be more sensitive to flame instability than atomic absorption or fluorescence needs to be explained. Concept introduction: Spectral lines help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range as compared to the frequencies nearby. Fluorescence is the process by which a substance absorbing electromagnetic radiation emits light. In a defined space, the amount of a substance gives its concentration. A capacity of substance to absorb specific wavelength light gives its absorbance.
