WebbThis interference needs to be controlled to attain good results of analysis. Some of the commonly encountered interference processes in flame photometry are: Spectral interferences, 2) Ionisation interferences, 3) Cation-anion interferences, Cation-cation interferences, and. Oxide formati on interferences. Flame Photometry (Chapter 4) 107. 4.2. WebbThe flame photometer A traditional and simple method for determining sodium and potassium in biological fluids involves the technique of emission flame photometry . This relies on the principle that an alkali metal salt drawn into a non-luminous flame will ionise, absorb energy from the flame and then emit light of a characteristic wavelength as the …

WebbPRINCIPLE OF FLAME PHOTOMETRY. Flame photometry is a method used for the determination of elements which can be easily excited for example, alkali and alkaline earth metals. This method is based upon the measurement of intensity of radiation emitted, in the visible region, when a metal atom is introduced into a flame. Webb17 dec. 2024 · The fundamental property which makes all photometry viable is due to the excitation and relaxing of electrons within the ion.
