WebFlame photometers are also very cost effective and easy to use. • In a flame photometer, the solution is aspirated through a nebulizer (or aspirator) into the flame. After the sample matrix evaporates, the sample is atomized. Atoms then reach an excited state by absorbing heat from the flame. Webpurpose low temperature flame photometry provides the most reliable and convenient procedure available. Flame Photometer Operating Data The analysis of alkali and alkaline earth metals by flame photometry has two major advantages. 1. Their atoms reach the excited state at a temperature lower than that at which most other elements are excited. 2. tsk caterham https://marbob.net
