The principle of flame photometry depends on
WebbThe principle of flame photometer is based on the measurement of the emitted light intensity when a metal is introduced into the flame. The wavelength of the colour gives information about the element and the colour of the flame gives information about the amount of the element present in the sample. Webb1 dec. 2024 · The principle of flame photometry is based on the fact that the compounds of some elements can be thermally dissociated in a flame and that some of the atoms …

Webb• explain the principle of flame photometry, • draw a schematic diagram illustrating different components of a flame photometer, • enlist the applications of flame photometry, • discuss the factors affecting flame photometric determinations, and • state the merits and limitations of the flame photometric technique. WebbTheory: When a solution containing metallic salt is sprayed into flame, the solution dries out by leaving a fine residue of neutral atoms. These neutral atoms absorb the thermal energy of the flame and get excited to their higher energy state and thereafter return to ground state. During return to ground state, the excited atoms lose the ...
