Answer :

A single beam flame photometer contains only one set of optics, which means it has a single light path for measuring the intensity of light emitted by excited metal ions in a sample. The main components include:

  1. Nebulizer: Converts the liquid sample into an aerosol mist.
  2. Flame: Excites the metal ions, causing them to emit light at characteristic wavelengths.
  3. Optics: A single set of lenses or mirrors focuses the emitted light.
  4. Monochromator/Filter: Isolates the specific wavelength of light corresponding to the element being measured.
  5. Detector: Measures the intensity of the isolated light wavelength.
  6. Readout Device: Displays the measurement results.

This single pathway setup allows the instrument to detect and quantify the concentration of specific metal ions in the sample.
