Flame Photometer

The Instrument:

Flame Photometry is a technique used to determine the concentration of certain metal ions like Sodium, Potassium, Lithium, Calcium and Barium. The International Union of Pure and Applied Chemistry (IUPAC) Committee on Spectroscopic Nomenclature has named this technique as Flame Atomic Emission Spectrometry (FAES). It is based on the measurement of the emitted light intensity when a metal is introduced into the flame. The wavelength of the color gives information about the element (Qualitative) and the color of the flame gives information about the amount of the element present in the sample (Quantitative).
