FP6450 flame photometer Introduction
The flame photometer is an analytical instrument based on the emission spectrum. For example, when the salt is placed in a fire, the flame is yellow. This is because the outer layer of the sodium atom in the salt absorbs the heat of the flame and transitions to the excited level, and then the stimulated level returns to the normal state. It is necessary to release energy, which is characterized by a spectral line that emits a wavelength specific to the sodium atom—the yellow spectrum (main wave 5893A). The heat of the flame can be used to illuminate the atoms of an element, and the intensity of the spectral energy is measured by an instrument to determine the level of an element in the substance. This type of requirement is called a flame photometer.
