Flame emission spectrophotometry
WebThere are four main stages which occur during this flame emission spectroscopy. 1. Evaporation: The sample containing metal particles is dehydrated by the heat of the flame and the solvent is evaporated. 2. Atomisation: At this stage the metal ions that were in the solvent are reduced to metal atoms. For example, Mg2+ (aq) + 2e → Mg (g). WebThe term “flame emission spectrometry” (FES) or “ flame photometry ” is an atomic optical emission spectroscopy technique that uses the flame as the source of atoms excitation.
