Flame Atomic Emission Spectroscopy. A photoelectric flame photometer is an instrument used in inorganic chemical analysis to determine the concentration of certain metal ions among them sodium potassium calcium and lithium. Flame Photometry is based on measurement of intensity of the light emitted when a metal is introduced into flame.
It is suitable for qualitative and quantitative determination of several cations especially for metals that are easily excited to higher energy levels at flame. Agricultural Applications of Flame Photometry. Flame photometer can be used to determine the concentration of certain metal ions like sodium potassium lithium calcium and cesium etc.
