Flame photometry is used in various industries like chemicals , soils, agriculture, pharmaceuticals, glass and ceramics, in plant materials and water, oceanography, and in biological and microbiological laboratories.
- It is used in determination of potassium, sodium, magnesium and calcium in biological fluids like serum, plasma, urine etc, is routinely carried out by flame photometer.
- Analysis of industrial water, natural water for determining elements responsible for hard water (magnesium, barium, calcium etc.) is standard procedure in many laboratories.
- Soil samples are routinely analysed mainly for sodium and potassium and also for calcium and magnesium (after removing other interfering elements) by flame photometer.
- Some important elements which are commonly determined by this method are aluminium, barium, calcium, chromium, copper, iron, lead , magnesium, potassium, zinc, manganese, and strontium.
- In glass industry, flame photometry is used in determining of sodium, potassium, boron, lithium etc.
- In cement industry, this method is used in estimation of sodium, potassium, calcium, magnesium, manganese, as well as lithium.
- Flame photometry is extensively used in estimation of alkali-alkaline earth metals as well as other metals present in metallurgical products, catalysts, alloys etc.
- Flame photometry has also been used in determination of certain metals like lead, manganese, in petroleum products like gasoline, lubricating oils and organic solvents.
- Analysis of ash by flame photometer is routinely carried out in various industries for estimating alkali and alkaline earth metals as their oxides.
