Flame photometry cannot be used for the direct determination of each and every metal atom. A number of metal atoms cannot be analysed by this method. The elements such as carbon, hydrogen and halides cannot be detected due to their non-radiating nature.
Summary A flame photometer technique suitable for single optical system instruments is described which gives excellent results for calcium, potassium and sodium in milk. The method consists essentially of determining the relative spectral intensity of the element in an unknown solution followed quickly by the determination of the intensity of the …

alkali metal salt [7]. Flame photometer is an optical device to measure the colour intensity of substances, such as sodium, potassium that have been aspirated into a flame [3]. The objective of this study was to determine the Potassium content of Alfalfa which were treated with different doses of gamma radiation by flame photometry method.
A study was made of the effect of uranium on sodium, potassium, and calcium radiation as well as the effect of aluminum and vanadium on calcium radiation in an acetylene-air flame. A method is described for the determination of sodium, potassium, and calcium in uranlum and its compounds by flame photometry without separation of uranium …
