Sinopsis

Flame emission (FE) spectrophotometry separates and detects the emission bands produced when an element is vaporized. An example of an instrument using atomic emission is an Inductively Coupled Plasma (ICP) Spectrometer, whilst an example of one using absorption energy is an Atomic Absorption Spectrometer. An emission spectrometer can be identical to an absorption system except that no external light source is used to excite the atoms. Cage is made of float glass for safety and visibility. is a scientific instrument based on flame testing. Instrumental methods of analysis rely on machines.
