The instrumentation of Flame Photometry is relatively straightforward, comprising several key components:
1) Sample Introduction System
Nebulizer: Converts liquid sample into an aerosol.
Spray Chamber: Removes large droplets, allowing only fine mist to enter the flame.
2) Flame and Burner System
Fuel and Oxidant: Commonly air-acetylene or air-propane flames are used.
Burner Head: Provides a steady flame and allows optimal atomization.
3) Optical System
Filters or Monochromators: Select the characteristic wavelength of the element being analyzed.
Interference Filters: Allow narrow wavelength bands to pass through.
Monochromators: Use prisms or diffraction gratings for wavelength selection.
4) Detector
Photocells or Photomultiplier Tubes: Convert the light signal into an electrical signal proportional to the intensity.
Amplifiers: Enhance the electrical signal for measurement.
5) Readout Device
Analog or Digital Meters: Display the measured signal.
Data Acquisition Systems: For recording and analyzing data.
