A photoelectric flame photometer is a machine used in inorganic chemical analysis to find out the concentration of certain metal ions, among them sodium, potassium, lithium, and calcium.
Flame photometry is crude but cheap compared to flame emission spectroscopy, where the emitted light is analyzed with a monochromatic. Its position is like to that of the colorimeter (which uses filters) compared to the spectrophotometer (which uses a monochromator). It also has the choice of metals that could be analysed and the limit of detection are also considered. |
