Flame photometry is a branch of atomic spectroscopy and it is a kind of emission spectroscopy broadly used to determine the concentration of some metal ions such as potassium (K), sodium (Na), calcium (Ca), lithium (Li), cesium (Cs) and biological fluids, etc. in the inorganic chemical analysis. The metal ions used in the spectrum in the photometry are in the form of atoms. The flame photometer can be useful for qualitative and quantitative analysis of elements. The radiation emitted by the photometer is characteristic of the individual metal. Therefore, with the use of a flame photometer, we can identify the particular element present in the sample solution.
Applications of flame photometry in the environmental analysis:
The environmental applications of flame photometry include determination of alkali and alkaline earth elements by conducting the flame test, analysis of water, monitoring of soil qualities, control of potassium, sodium, and magnesium of wastewater, control of fertilizer residues in the soil, etc.
Applications of flame photometer in the pharmaceutical industry:
Flame photometry used for the determination of sodium and potassium ion concentration in pharmaceutical reagents such as the infusion solutions, for example, sodium chloride solution (NaCl), and ringer solution. It is also used for the determination of metal ions in some pharmaceuticals.
Applications of flame photometer in the cement industry:
It is useful in construction and cement industries for the review of potassium, sodium, and calcium content.
Applications of flame photometry in the food industry:
The quality and limits of sodium (Na+) and potassium (K+) can be monitored and controlled with a flame photometer in the food industries.
Applications of flame photometer in the beverage industry:
It is essential to determine the concentrations of various metals and elements in different liquids, such as soft drinks, alcoholic beverages, vegetable juices, and fruit juices hence it is used in the beverage industry.
Applications of flame photometry in the biological fluid:
The concentrations of Na+ and K+ ions are extremely significant for the operation of various metabolic processes in the human body, which they can determine in the flame by blood serum samples.
Applications of flame photometer in the chemical industry:
It is extremely useful in different manufacturing as well as in chemical industries to monitor and concentration determinations of potassium and sodium in final products.
